Detailed Description
Hereinafter, embodiments of the present invention will be described in detail. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
The invention discloses a low-cost high-performance magnesium alloy section, which comprises the following components in percentage by weight: 0.1 to 0.8 percent of Mn, 0.1 to 1.0 percent of Zn, 0.1 to 1.0 percent of Ce, and the balance of Mg and inevitable impurities. The invention abandons the traditional magnesium alloy section bar preparation process that a large amount of rare earth elements such as Y, La, Gd and the like are added, and prepares the microalloyed magnesium alloy section bar by uniformly mixing Mg with trace elements such as Mn, Zn and Ce. Although a large amount of rare earth elements such as Y, La, Gd and the like added in the traditional process can obviously improve the strength of the magnesium alloy section, the rare earth elements are expensive and have large addition amount, and the smelting process is relatively complex. According to the invention, the trace elements Mn, Zn and Ce are used for replacing a large amount of rare earth elements in the traditional process, so that the crystal grains of the internal structure of the magnesium alloy section are refined, the texture is weakened, the comprehensive performance of the magnesium alloy section is obviously improved, and the cost of the added trace elements is effectively controlled.
In the embodiment, the low-cost high-performance magnesium alloy section comprises the following components in percentage by weight: 0.2 to 0.7 percent of Mn, 0.2 to 0.7 percent of Zn, 0.2 to 0.7 percent of Ce, and the balance of Mg and inevitable impurities. By further controlling the use amount of the trace elements Mn, Zn and Ce, the components in the magnesium alloy section are more accurate, and the stability of the comprehensive performance of the magnesium alloy section is improved.
In the embodiment, the low-cost high-performance magnesium alloy section comprises the following components in percentage by weight: 0.2 to 0.4 percent of Zn, 0.2 to 0.4 percent of Ce, and the balance of Mg and inevitable impurities. By further controlling the use amount of the trace elements Mn, Zn and Ce, the components in the magnesium alloy section are more accurate, and the stability of the comprehensive performance of the magnesium alloy section is further improved.
The invention also discloses a preparation method of the low-cost high-performance magnesium alloy section, which comprises the following steps:
s1: uniformly mixing the raw materials according to the proportion of the magnesium alloy section;
s2: putting the uniformly mixed raw materials into a protective atmosphere smelting furnace for smelting at the smelting temperature of 700-720 ℃, preserving heat for 10-30 min, and then casting into a phi 130mm ingot;
s3: putting the cast ingot into a heat treatment furnace for heat treatment at the temperature of 100-400 ℃ for 1-10 hours to obtain the ingot with the structure of single-phase solid solution;
s4: and (3) extruding the single-phase solid solution cast ingot in extrusion equipment at the extrusion temperature of 80-300 ℃ to obtain a magnesium alloy profile finished product.
In the process of preparing the magnesium alloy section, the raw materials of the magnesium alloy section according to the proportion can obtain the magnesium alloy section with excellent performances in all aspects under the production process by controlling the smelting temperature, the heat preservation time, the heat treatment temperature, the heat preservation time, the extrusion temperature and the extrusion speed. The single-phase solid solution obtained in the heat treatment process refers to an alloy phase formed by completely dissolving solute atoms in a solid metal solvent, and can obviously improve the mechanical property, the corrosion resistance and the pressure processing property of the magnesium alloy section.
In this example, in step S3, the heat treatment was carried out for 4 to 6 hours. The heat preservation time of the further precise heat treatment enables the internal structure of the cast ingot to be more uniform in the heat treatment process, so that the performance of the magnesium alloy section is improved.
Specifically, an example shows that the magnesium alloy profile comprises the following components in percentage by weight: 0.2-0.4% of magnesium alloy, 0.2-0.4% of Zn, 0.2-0.4% of Ce, and the balance of Mg and inevitable impurities, wherein the magnesium alloy section is processed into a magnesium alloy bar by the preparation method, and the diameter of the bar is 16 mm. The detection of related experimental equipment shows that the grain size of the cast ingot after smelting and pouring is 410-430 μm; the elongation percentage after being extruded into a bar is 18 to 22 percent, the tensile strength is 332MPa to 346MPa, the yield strength is 300MPa to 305MPa, and the grain size is 5.6 mu m to 6.5 mu m. The detection data show that the magnesium alloy section prepared by adding the trace elements Mn, Zn and Ce has good comprehensive performance, and the manufacturing cost of the magnesium alloy section is effectively controlled.
Finally, it should be noted that: while there have been shown and described what are at present considered the fundamental principles and essential features of the invention and its advantages, it will be apparent to those skilled in the art that the invention is not limited to the details of the foregoing exemplary embodiments, but is capable of other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
