Definitions
- AZ31, AZ61, etc. are used as the most versatile wrought magnesium alloys obtained by rolling. Elements such as A1 contained in these materials increase the strength of magnesium, but on the contrary, deteriorate ductility and toughness. In general, when the strength increases, the drawability, elongation, bending performance, or deep drawability, which is an index of ductility and toughness, deteriorates conversely.
- the total draft is desirably 5.0% or more and 30.0% or less. If the total draft is less than 5.0%, sufficient bending workability cannot be obtained. Conversely, if it exceeds 30.0%, the strain on the rolled sheet becomes too large and the possibility of cracking increases.
- the total draft is calculated by the following formula.
- the magnesium alloy sheet is subjected to a solution treatment at 350 to 450 ° C for 1 hour or more.
- a solution treatment at 350 to 450 ° C for 1 hour or more.
- the solution treatment temperature is less than 350 or less than 1 hour, the effect of sufficiently removing the residual stress or reducing the texture is small.
- the temperature exceeds 450 ° C the effects such as the removal of residual stress will be saturated and the energy required for the solution treatment will be wasted.
- the upper limit of the solution treatment time is about 3 hours.
- the magnesium alloy sheet After rolling, it is desirable to subject the magnesium alloy sheet to a heat treatment at 100 to 350 ° C. By this heat treatment, the residual stress or strain introduced by the working can be removed to improve the mechanical properties.
- the heat treatment time is preferably about 5 minutes to 3 hours. If the temperature is less than 100 ° C or less than 5 minutes, recrystallization is insufficient and the strain remains, and the temperature exceeds 350 ° C. 1
- a magnesium alloy sheet having a minimum bending modulus B of 2 or less can be easily obtained.
- the plastic strain ratio r in the tensile direction parallel to the rolling direction may be less than one.
- the plastic strain ratio r gn not only in the direction parallel to the rolling direction but also at least in the direction orthogonal to the rolling direction must be 2 or less. Since found to be preferable.
- the value shall be 2.0 or less, except for the plastic strain ratio in the tensile direction parallel to the rolling direction other than the orthogonal tensile direction, e.g., the plastic strain ratio r value in all other tensile directions shall be 2.0 or less. can do.
- the plastic strain ratio r B value in the tensile direction parallel to the rolling direction is more preferably 1.2 or less.
- the r value can be controlled to 2.0 or less by controlling, for example, the requirements specified in the above-described method of the present invention, specifically, the sheet temperature before rolling and the roll surface temperature.
- the plastic strain ratio r value is the true strain in the sheet thickness direction at the true strain d w in the sheet width direction and the true strain d t in the sheet thickness direction generated when the strain is given in the tensile direction in the tensile test.
- the ratio of the true strain d w in the sheet width direction to the strain d t is defined as d.
- the plastic strain ratio when the tensile direction is parallel to the rolling direction is r.
- R 9 is the plastic strain ratio when the tensile direction is perpendicular to the rolling direction. Value.
- FIG. 1 is an explanatory view of a bending test
- FIG. 2 is a schematic explanatory view showing rolling conditions of the present invention
- FIG. 3 is a graph showing X-ray diffraction intensity in an example of a magnesium alloy sheet of the present invention
- FIG. 3 is an explanatory diagram illustrating a state in which a tensile stress is applied to a plate-shaped test piece.
- AZ31 was selected as the magnesium alloy material used for rolling and rolling was performed.
- the chemical composition (unit: mass%) of AZ31 used was 3.06% 0.90% Zn-0.01% Si-0.57% Mn, with the balance being Mg and unavoidable impurities.
- the value of the minimum bending coefficient B shown in the following equation was considered as a representative characteristic value.
- This minimum bending factor B can be evaluated only when surface cracking does not occur in the bending test, and when surface cracking occurs (X in Table 2), the value of minimum bending factor B cannot be evaluated. It was taken.
- the minimum bending factor B means that the smaller the value, the better the bending workability.
- the smallest value of the minimum bending coefficient B for that sample was adopted.
- the magnesium alloy sheet heated to more than 100T: before rolling (No.1-l to No. 9) was heated to over 100 ° C before rolling.
- the minimum bending coefficient B was larger and the bending workability was poorer than those in which the roll surface temperature was heated to 100 ⁇ or higher.
- the ones heated to more than 100 ° C before rolling have a minimum bending modulus B of 2.0 or more, but the sheet before rolling under conditions where the roll surface temperature is heated to 100 ° C or more.
- the minimum bending coefficient B was 2.0 or less. From this, it can be said that it is preferable to set the temperature to 100 ° C or lower before rolling.
- the rolling conditions of the present invention consist of one or more rolling steps of multiple passes, but at least one rolling including the final pass must be performed by non-preheat rolling.
- the rolling conditions of the pass before the non-preheat rolling are not particularly limited. Rolling including non-preheat rolling It is necessary to adjust the total rolling reduction to 5.0% or more and 30.0% or less.
- rolling including non-pre-press rolling it is desirable to apply lubricating oil to the rolled plate before rolling, and it is also desirable that the rolling speed be l.Om/min or more. If the rolling speed is less than l.Om/min, the original effect of non-preheat rolling can be obtained because the temperature inside the sheet rises more than necessary during rolling and the deformation mechanism changes due to the decrease in strain rate. hard.
- the finish rolling of the magnesium alloy was performed in the same way as in Test Example 1, with a thickness of 12 bands, 8 mm, and 6 mm.
- the AZ31 plate was solution-treated at 400 ° C for 1 hour.
- each r-value was determined such that the average of the r-value when the elongation was 5% and the r-value immediately before the fracture was the r-value when the elongation was less than 5%.
- Equation for calculating the average crystal grain size as described in Annex 3 of JIS G 0551 on the basis of (d m 1 / m, d m:: Average particle size, m the number of crystal grains per 1 mm 2 of the surface of the test piece) The average grain size of the crystal grains was determined.
- non-preheated samples No. 2-1 and 2- have low anisotropy, specifically, the plastic strain ratio r in the tensile direction parallel to the rolling direction. .
- the plastic strain ratio r 9 in the tensile direction perpendicular to the rolling direction It can be seen that the value is 2.0 or less.
- the diffraction peak intensity ratio ⁇ ⁇ / ⁇ ⁇ ⁇ is as small as less than 10.
- the elongation is 10% or more in both the tensile direction parallel to the rolling direction and the tensile direction perpendicular to the rolling direction.
- Samples Nos. 2-1 and 2-2 that had been subjected to non-preheat rolling in this way had low anisotropy and had excellent elongation. You can see that it has excellent properties.
- the magnesium alloy sheet of the present invention is expected to be widely used for personal computers, mobile phone housings, and other products that aim to reduce the weight and that require strength and toughness.
