Description
One embodiment of the present invention relates to a magnesium alloy and a method of making the same.
The addition of aluminum (Al) to the magnesium alloy can improve the casting of the magnesium alloy. For this reason, alloys for casting such as AZ91 containing about 9 wt% of aluminum (Al) are widely used in automobile parts and the like. On the other hand, when a small amount of aluminum (Al) is added, the warm formability of the magnesium alloy can be improved. Therefore, an aluminum alloy such as AZ31 containing about 3 wt% of aluminum (Al) has been developed.
However, AZ31 alloys developed for all new materials are not yet universally applied. One of the reasons for this is that the mechanical properties such as tensile strength and elongation are lower than that of the aluminum-based alloy. Therefore, it is necessary to improve the tensile strength and elongation to apply a magnesium alloy such as AZ31 to a plate or an outer plate of an automobile.

BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention and the manner of achieving them will become apparent with reference to the embodiments described in detail below with reference to the accompanying drawings. However, it is to be understood that the present invention is not limited to the disclosed embodiments, but may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. It is intended that the disclosure of the present invention be limited only by the terms of the appended claims. Like reference numerals refer to like elements throughout the specification.
Thus, in some embodiments, well-known techniques are not specifically described to avoid an undesirable interpretation of the present invention. Unless defined otherwise, all terms (including technical and scientific terms) used herein may be used in a sense commonly understood by one of ordinary skill in the art to which this invention belongs. Whenever a component is referred to as "including" an element throughout the specification, it is to be understood that the element may include other elements, not the exclusion of any other element, unless the context clearly dictates otherwise. Also, singular forms include plural forms unless the context clearly dictates otherwise.
The magnesium alloy, which is one embodiment of the present invention, comprises 1.0 to 5.0 wt% of aluminum (Al), 0.3 to 3.0 wt% of zinc (Zn), 0.01 to 3.0 wt% of antimony (Sb) 0.01 to 1.0% by weight of strontium (Sr), the balance magnesium (Mg) and other unavoidable impurities.
First, the reason for limiting the above components will be described.
Aluminum (Al) not only contributes to improving the fluidity of the magnesium alloy, but also enhances the strength by forming precipitates for strengthening magnesium (Mg) and Mg-Al. It may also form additional antimony (Sb) and Al-Sb precipitate phases.
Therefore, it is possible to add 1% by weight or more of the magnesium or aluminum element in order to form each precipitation phase and to expect the strength improvement as described above. However, when it is added in an amount exceeding 5% by weight, the moldability can be reduced due to reduction of ductility.
Adding a small amount of zinc (Zn) to the magnesium alloy can be expected to enhance the solvency. However, if the addition amount is excessively large, mechanical properties such as ductility may be reduced due to segregation.
Therefore, 0.3 wt% or more can be added in order to expect solid solution strengthening effect, but when it exceeds 3 wt%, coarse precipitation phase is formed and strength can be reduced
Antimony (Sb) can form a Mg-Sb precipitate phase with magnesium (Mg), which is a base metal. In addition, aluminum (Al) and Al-Sb precipitation phases to be added together can be formed, thereby contributing to improvement of tensile strength.
More specifically, even when a trace amount of about 0.01% by weight is added, the tensile strength can be improved. However, when it is added in an amount exceeding 3% by weight, a coarse precipitation phase is formed and the strength and ductility can be reduced.
Strontium (Sr) can form Mg-Sr precipitation phases with magnesium (Mg), which is a base metal. In addition, aluminum (Al) and Al-Sb precipitation phases to be added together can be formed, thereby contributing to improvement of tensile strength. In addition, it also contributes to an improvement in the tensile strength or an improvement in elongation due to grain refinement.
More specifically, even when a trace amount of about 0.01% by weight is added, tensile strength and elongation can be improved due to grain refinement or precipitation. However, when it is added in an amount exceeding 1% by weight, a coarse precipitation phase may be formed and the strength and ductility may be lowered.
Therefore, by utilizing the property of antimony (Mg-Sb) to form a fine dispersion phase with magnesium, the role of strontium (Al-Sr) to form a fine dispersion state of aluminum and the grain refining function of strontium (Sr) Magnesium alloy of the desired strength and ductility can be obtained.
More specifically, the average crystal grain size of the magnesium alloy satisfying the above-described components and composition ranges may be 4 to 10 탆. The yield strength of the magnesium alloy may be 160 to 260 MPa. The tensile strength of the magnesium alloy may be 230 to 350 MPa, and the elongation of the magnesium alloy may be 10 to 30%.
According to another aspect of the present invention, there is provided a method of manufacturing a magnesium alloy, comprising: preparing a molten metal; Casting the molten metal to produce a magnesium alloy; Rolling the magnesium alloy to produce a rolled material; And heat treating the rolled material.
In addition, in the magnesium alloy manufacturing method according to an embodiment of the present invention, the magnesium alloy can be manufactured and heat-treated by an extrusion process as well as a rolling process.
More specifically, the step of heat-treating the rolled material may include: a step of solubilizing the rolled material; Cooling the solution-applied rolled material; And aging the cooled rolled material.
The heat treatment of the rolled material may be performed at a temperature ranging from 350 to 450 ° C for 10 to 20 hours.
Thereafter, the step of cooling the solution-treated rolled material can be water-cooled to a range of 1 to 100 ° C / h.
Aging the cooled rolled material may be carried out at a temperature of 150 to 250 DEG C for 15 to 25 hours.
More specifically, when the rolled material is subjected to the subsequent heat treatment in the temperature and time range, a magnesium alloy having improved yield strength and tensile strength without decreasing the elongation rate can be provided.
The molten metal may be used in an amount of 1.0 to 5.0 wt% of aluminum (Al), 0.3 to 3.0 wt% of zinc (Zn), 0.01 to 3.0 wt% of antimony (Sb) By weight, strontium (Sr): 0.01 to 1.0% by weight, magnesium (Mg), and other unavoidable impurities. At this time, the components and the composition ranges of the molten metal are the same as those of the magnesium alloy described above, and thus a detailed description thereof will be omitted.
The step of casting the molten metal to produce the magnesium alloy may be a direct chill casting method, a continuous casting method, a metal casting method, or a combination thereof. However, the present invention is not limited thereto. It is possible.
In addition, since the above method is a general process, a detailed description will be omitted.
The step of rolling the magnesium alloy to produce a rolled material may be performed at a temperature ranging from 200 to 250 ° C. In addition, the magnesium alloy may be rolled 5 to 8 times.
The average crystal grain size of the magnesium alloy produced by the above method may be 4 to 10 탆. The yield strength of the magnesium alloy may be 160 to 260 MPa. The tensile strength of the magnesium alloy may be 230 to 350 MPa, and the elongation of the magnesium alloy may be 10 to 30%.
Example
Various kinds of magnesium alloys having the chemical compositions shown in Table 1 were melted and then cast into a cylindrical shape billet having a diameter of 50 mm through gravity casting.
Thereafter, it was machined into a rectangular shape with a thickness of 20 mm, a width of 40 mm, and a length of 300 mm through machining. More specifically, the machined slabs were made of a rolled material having a thickness of 0.8 mm at a temperature of 200 to 250 ° C in only 5 to 8 passes.
The rolled material was heat-treated for strength improvement, and the curing heat treatment was water-cooled at a rate of 10 ° C / h after solution treatment at 415 ° C for 12 hours. Thereafter, the resultant was aged at 200 DEG C for 20 hours.
The tensile test piece of the rolled material completed the heat treatment was prepared to a thickness of 0.7 mm according to ASTM B557M standard, and the tensile test was conducted by a universal testing machine.
(MPa)
Strength (MPa)
As a result, as shown in Table 1, it can be seen that the yield strength, the tensile strength and the elongation ratio of the Examples are all superior to those of the Comparative Examples.
More specifically, FIG. 1 illustrates a rolled material according to an embodiment of the present invention. 2 shows a tensile test specimen of a rolled material according to an embodiment of the present invention.
Therefore, as shown in FIGS. 1 and 2, it can be seen that the rolled material and the tensile test piece according to one embodiment of the present invention have excellent elongation and moldability.
More specifically, in Comparative Example 2 and Example 5 of Table 1, although the composition ranges of aluminum and zinc are the same, in Comparative Example 2, which does not contain antimony and strontium components, It can be seen that the strength, tensile strength, and elongation are all for heat.
This can be attributed to the effect of the precipitation phase and grain refinement due to the addition of antimony and strontium and the effect of the subsequent heat treatment process after the magnesium alloy processing.
Therefore, the present invention is superior in strength and ductility to the comparative example from the above characteristics.
While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, You will understand.
