Definitions
- the present invention relates to a titanium thin plate, and more particularly to a high-strength titanium thin plate having excellent workability and high surface hardness and excellent workability that can be suitably used for speaker diaphragms and the like.
- Titanium materials have high specific strength and excellent corrosion resistance, and are widely used as materials for chemical plants, construction, and many other industrial materials, as well as for consumer products such as camera bodies, watches and sports equipment. Used for applications.
- Titanium materials are no exception and are often required to have not only excellent workability but also high strength. However, in general, workability decreases when the strength is increased. For titanium materials, attempts are made to optimize the balance between strength and workability by controlling the oxygen content, iron content, crystal grain size, and the like. I have been.
- Patent Document 1 the ductility of a titanium plate is increased by increasing the Fe content (Fe: 0.1 to 0.6 mass%) while keeping the O (oxygen) content in the titanium material at a predetermined value.
- a titanium plate is disclosed in which the strength is improved while suppressing the decrease in the thickness, and the formability is improved so that the average particle size is 10 ⁇ m or less.
- Patent Document 2 discloses a Ti plate material having good forming workability in which the Fe content is 300 ppm or more and the [Fe + O + N + H] content is 1500 ppm or less, and the amount of nitrogen and hydrogen is limited in addition to the amount of iron and oxygen. ing.
- Patent Document 3 the amount of iron, the amount of oxygen, and further the amount of nickel and chromium are specified within a predetermined range so that good formability can be maintained even when an inexpensive raw material with low purity is used.
- a method for producing a pure titanium plate having an average particle size of 20 to 80 ⁇ m is disclosed.
- Patent Document 4 discloses a method for producing a titanium foil having excellent formability. According to this technique, titanium foil having a thickness of 25 ⁇ m is rolled under predetermined rolling conditions, and the crystal grain size is determined according to ASTM No. It is said that a good Erichsen value is ensured by controlling so as to be 12 to 14.
- a titanium foil having a thickness of 0.2 mm or less is required to have good shape retention after molding.
- good shape retention can be ensured, but on the other hand, there is a problem that good workability cannot be obtained.
- the part which received the big process improves intensity
- Patent Document 5 discloses a technique of performing electrolytic pickling after forming a layer containing titanium carbide and / or nitride as an inner surface layer by bright annealing or vacuum annealing. This technology prevents adhesion of the titanium base material to the mold by suppressing contact between the soft titanium base material and the mold, and at the same time forms an oxide layer with excellent lubricity during pressing on the titanium surface. Is. According to this technique, titanium carbide and / or nitride can be prevented from coming into contact with the mold, and wear of the mold can be prevented.
- titanium foil having a thickness of 0.2 mm or less is rarely subjected to severe processing as disclosed in Patent Document 5.
- processing of speaker diaphragms is often molded into a dome shape by applying internal pressure, and there is less contact with the mold during processing compared to molding with a general thin plate press, and surface lubrication of the material itself Sex doesn't matter so much. Therefore, even if the technique described in Patent Document 5 is applied, the workability improvement effect due to the lubricating effect of the oxide is not exhibited.

- Japanese Patent No. 4605514 Japanese Unexamined Patent Publication No. Sho 63-103043 Japanese Patent No. 3228134 Japanese Patent No. 2616181 Japanese Unexamined Patent Publication No. 2009-97060
- the present invention has been made in view of such circumstances, and an object of the present invention is to provide a titanium thin plate having a thickness of 0.2 mm or less and excellent in shape retention and workability.
- the present inventors pay attention to the hardness of the surface of the titanium foil, and if the surface is hard and the inside is softer than the surface, it is possible to achieve both shape retention and workability. Therefore, we investigated the methods for improving the workability and surface hardness of titanium thin plates.
- An effective means for improving the workability of titanium thin plates is to reduce the elements such as iron and oxygen. Although these elements are elements inevitably brought into production, it is necessary to limit them to a predetermined amount or less as described in Patent Documents 1 to 3 described above.
- the next possibility is crystal grain coarsening.
- coarsening twin deformation which is important for the workability of the titanium material can be easily generated, and the workability is improved. Since the crystal grain size is controlled in the final finish annealing step, it can be easily controlled by changing the annealing conditions.
- the grain size is generally in the range of 10 to 60 ⁇ m, so that a phenomenon in which elongation decreases due to coarsening of crystal grains does not occur.
- Intruded carbon and nitrogen form TiC and TiN and cause solid solution strengthening, so that the surface hardness is high and the shape retention is improved even in an ultrathin titanium thin plate having a thickness of 0.2 mm or less. .
- the penetration depth of carbon, nitrogen, and oxygen is in the range of 200 nm to 2 ⁇ m from the surface. That is, the region of the hardened layer formed by the penetration of carbon, nitrogen, and oxygen needs to be in the range of 200 nm to 2 ⁇ m from the surface.
- the present invention has been made on the basis of the findings of the above study, and the gist of the present invention is a high-strength titanium thin plate excellent in the following workability. That is, a titanium thin plate having a thickness of 0.2 mm or less, bulk Fe is 0.1 mass% or less, O (oxygen) is 0.1 mass% or less, and plate thickness (mm) / particle diameter (mm) A titanium thin plate satisfying ⁇ 3, satisfying a particle size of ⁇ 2.5 ⁇ m, having a hardened layer on the surface, and a region of the hardened layer having a depth of 200 nm to 2 ⁇ m from the surface.
- titanium thin plate of the present invention is subjected to finish annealing (bright annealing) at 500 ° C. or more and 850 ° C. or less by BAF (batch heat treatment) or continuous annealing after cold rolling, stable workability is ensured. desirable.
- the “titanium thin plate” referred to here is a pure titanium for industrial use as defined in JISH4600, and refers to a thin plate or foil having a plate thickness of 0.2 mm or less.
- particle diameter means an average particle diameter determined by a quadrature method specified in JISH0501. This may be emphasized and referred to as “average particle size”.
- the “hardened layer” means carbon, nitrogen, oxygen derived from the rolling oil remaining on the surface during annealing, oxygen, nitrogen, carbon concentration formed by nitrogen and oxygen gas contained in the gas atmosphere of the annealing furnace. Refers to a chemical layer.
- the titanium thin plate of the present invention is a titanium thin plate having a thickness of 0.2 mm or less and imparted with excellent workability and high surface hardness. For example, it is used for various applications including acoustic parts (speaker diaphragms, etc.). It is a titanium thin plate (foil) that can be suitably used.
- the titanium thin plate of the present invention is a titanium thin plate having a thickness of 0.2 mm or less, wherein bulk Fe is 0.1 mass% or less, O (oxygen) is 0.1 mass% or less, and the plate thickness is (Mm) / particle diameter (mm) ⁇ 3 and particle diameter ⁇ 2.5 ⁇ m is satisfied, the surface has a hardened layer, and the region of the hardened layer has a depth of 200 nm to 2 ⁇ m from the surface.
- the purpose of the titanium thin plate having a thickness of 0.2 mm or less is to provide a high-strength titanium thin plate excellent in workability that can be suitably used for, for example, a speaker diaphragm.
- the bulk Fe is defined as 0.1 mass% or less for the following reason. That is, Fe is an element that stabilizes the ⁇ phase. When the ⁇ phase is present, growth of crystal grains is inhibited by the ⁇ phase during annealing. When the content exceeds 0.1 mass%, the effect becomes remarkable, so the Fe content is set to 0.1 mass% or less.
- the lower limit is not particularly limited, but in the case of industrial production, mixing of Fe is unavoidable, and since 0.01 mass% or more is included, the desirable lower limit is set to 0.01 mass%.
- the reason why the bulk O (oxygen) is defined to be 0.1 mass% or less is to suppress a decrease in workability.
- the addition of O increases the strength of the titanium thin plate, but the workability decreases, and the tendency becomes remarkable when the content exceeds 0.1 mass%. Therefore, the content of O is set to 0.1 mass% or less.
- the lower limit is not particularly limited. However, since O is inevitably mixed when it is industrially produced in the same manner as Fe, the desirable lower limit is set to 0.01 mass%.
- the bulk means the inside excluding the hardened layer formed on the surface of the titanium thin plate.
- the Fe concentration is 0.1 mass% or less
- the O concentration is 0.1 mass% or less.
- the reason why the particle size ⁇ 2.5 ⁇ m is satisfied is that, as shown in FIG. 1, when the particle size is less than 2.5 ⁇ m, the elongation greatly decreases and the workability decreases. .
- FIG. 1 is a diagram illustrating the relationship between crystal grain size and elongation in a tensile test of a titanium thin plate. As shown in the figure, when the crystal grain size is less than 2.5 ⁇ m, the strength is excessively increased even if there is no non-recrystallized grain, and the elongation is greatly reduced.
- plate thickness (mm) / particle size (mm) ⁇ 3 (hereinafter, “plate thickness (mm) / particle size (mm)” is also simply referred to as “plate thickness / particle size”) is satisfied. The reason is as follows.
- FIG. 2 is a diagram illustrating the relationship between stress and strain in a tensile test of a titanium thin plate (foil) having a thickness of 25 ⁇ m.
- particle size: 5.3 ⁇ m and “particle size: 12.3 ⁇ m” are measurement results for test pieces having average particle sizes of 5.3 ⁇ m and 12.3 ⁇ m, respectively.
- FIG. 2 in any of the test pieces, after a uniform elongation state has elapsed, local deformation is started, and breakage occurs. The local deformation amount is small, and the uniform deformation amount, that is, uniform elongation is an index of workability, and a decrease in this indicates a decrease in workability.
- FIG. 2 shows this state.
- the upper limit of the average crystal grain size range in which workability can be improved by coarsening is determined by the number of crystal grains existing in the plate thickness direction, that is, the ratio of plate thickness / grain size.

- the hardened layer is a concentrated layer of carbon, nitrogen, oxygen derived from the rolling oil remaining on the surface at the time of annealing, oxygen, nitrogen, and oxygen formed by nitrogen and oxygen gas contained in the gas atmosphere of the annealing furnace, A region containing 0.5 mass% or more of oxygen, a region containing 0.5 mass% or more of nitrogen, a region containing 0.5 mass% or more of carbon, or a total of 0.5 mass% or more of oxygen, nitrogen and carbon It is an area.
- the thickness of the hardened layer can be measured by GDS (Glow Discharge Optical Emission Analyzer).
- FIG. 4 is a diagram showing the relationship between the thickness of the hardened layer and the surface hardness of the titanium thin plate.
- the surface hardness increases as the hardened layer thickness increases.
- the thickness of the hardened layer is less than 200 nm, it is almost the same as the material hardness measured in the cross section of the material (shown in FIG. 4), and no increase in hardness is observed.
- the thickness of the cured layer is 200 nm or more.
- FIG. 5 is a diagram illustrating the relationship between the hardened layer thickness and elongation for a titanium thin plate having a thickness of 100 ⁇ m and a plate thickness / particle size ⁇ 3. As shown in FIG. 5, even if the plate thickness / particle size ⁇ 3, the cured layer thickness is 2000 nm (2 ⁇ m), because if the cured layer thickness is too thick, the elongation decreases and the workability decreases. The following.
- the titanium thin plate of the present invention is subjected to finish annealing at 500 ° C. or more and 850 ° C. or less by BAF or continuous annealing after cold rolling, it is desirable because stable workability is ensured.

- a hardened layer was formed by concentrating oxygen, nitrogen, or carbon on the surface of the plate with the rolling oil remaining on the surface of the plate or the gas atmosphere of the annealing furnace. The thickness (depth) of the hardened layer was adjusted by changing the remaining amount of rolling oil and the amount of nitrogen and oxygen in the atmosphere during bright annealing.
- each test piece after finish annealing was processed into a test piece having a parallel part width of 6.25 mm and a parallel part length of 50 mm, and then a tensile test was performed. Moreover, about each test piece, plate
