Description
Technical Field
The invention belongs to the technical field of solid solution strengthening processing of nonferrous metals, and relates to a preparation method of a high-conductivity Mg-Zn-Cu magnesium alloy.
Background
The conductivity of the Mg-Zn magnesium alloy in an as-cast state is 19.06-20.34 MS.m -1 And has great application potential under high temperature condition, and plays an important role in the application of 5G base station and mobile phone field. However, as the electronic industry continues to develop, the temperature of devices is kept within a safe range and the service life of electronic products is prolonged, so that highly conductive magnesium alloys are required to meet strict requirements.
The conductivity of Mg-Zn alloys decreases with increasing content of the alloying elements. This phenomenon is mainly caused by alloy atoms dissolved in the magnesium matrix. The solute atoms are different in size from the magnesium atoms, and therefore the crystal lattice of the magnesium alloy is distorted, eventually leading to a decrease in thermal conductivity.
In the Mg-Zn alloy, a precipitation phase in a solid solution process is formed by gathering Zn atoms, and when the intermediate temperature (about 100 ℃) is subjected to solid solution treatment, various precipitates of different types exist at the same time, so that the electrical conductivity of the alloy is improved while the alloy is hardened. The heat treatment sequence of the alloy is reported to be SSSS → pre-beta ‘ →β 1 ‘ (rod and bulk precipitate ≠ 0001) } Mg 4 Zn 7 ）→β 2 ‘ (mainly coarse particles | {0001} mg and some lath-shaped precipitates | {0001} mg 2 ) → beta equilibrium phase (MgZn or Mg) 2 Zn 3 ). The addition of Cu can raise the eutectic temperature of Mg-Zn alloy, so that the solution treatment can be carried out at a higher temperature to make more Zn and Cu dissolve in solution. Although researchers are concerned with Mg-Zn-Cu based magnesium alloysThe study is very intensive, but the relation between the electric conductivity and the structure evolution after the Mg-Zn-Cu series magnesium alloy is subjected to solid solution treatment is not explained.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The technical solution of the present invention is described in detail below with reference to the embodiments and the drawings, but the scope of protection is not limited thereto.
Example 1
Step 1, designing alloy components: in the embodiment, magnesium blocks, zinc blocks and copper wires are used as raw materials, and three groups of Mg-Zn-Cu series magnesium alloys are designed, and the following table specifically shows:
step 2, alloy smelting
This example prepares an alloy system using a box-type resistance furnace under a protective gas (argon). The following table specifically shows:
1) Melting magnesium ingot
When the temperature of the resistance furnace rises to 500 ℃, adding the preheated (200 ℃) magnesium block into a crucible, spraying the dried covering agent on the magnesium block, and introducing high-purity argon into the box-type resistance furnace for gas protection (magnesium is a very active metal element and is easy to react with O in the air at high temperature 2 And reacts with water vapor, affecting alloy properties); and when the temperature of the resistance furnace rises to 720 ℃, keeping the temperature for 20 min at a constant temperature to ensure that the magnesium blocks can be completely melted.
2) Adding zinc and copper
After the magnesium block is completely melted, opening a furnace cover, cleaning the surface of the solution by using a slag removing rod, then adding the preheated zinc block, spraying the dried covering agent, and closing the furnace cover to start heating. When the temperature rises to 750 ℃, the surface of the solution is cleaned by a slag removing rod for secondary opening, a preheated copper wire is added according to the test requirement, a covering agent is sprayed after stirring, a furnace cover is closed, and the temperature is kept for 5 min.
3) Refining of
When the furnace temperature is reduced to 720 ℃, cleaning slag on the surface of the melt, adding a refining agent, stirring for 1min, and starting refining. And finally, uniformly spraying a covering agent, closing a furnace cover, and preserving heat for 20 min after the furnace temperature is raised to 750 ℃.
4) Pouring
Keeping the temperature at 750 ℃ for 20 min, then reducing the furnace temperature to 740 ℃, cleaning the surface of the solution by a slag removing rod, and then casting the magnesium alloy melt into a preheated mold (200 ℃). And after the temperature of the die is naturally cooled to room temperature, taking out the sample from the die to obtain the as-cast alloy test bar.
Step 3, solution treatment
Respectively aligning three groups of alloys Mg-3Zn-1Cu; mg-3Zn-2Cu; and performing solid solution treatment on the Mg-3Zn-3 Cu. Before the solid solution treatment, carrying out cast Mg-3Zn-1Cu; mg-3Zn-2Cu; the Mg-3Zn-3Cu alloy (group A) samples were subjected to differential thermal analysis. The alloy has an endothermic peak on the DSC curve, which corresponds to the endothermic peak of the second phase of the alloy at 470 ℃. Therefore, in order to avoid the second phase in the alloy from being over-sintered, the solid solution temperature of the alloy is set to 430 ℃. Then, respectively carrying out cast Mg-3Zn-1Cu treatment on the cast Mg-3Zn-1Cu by using a vacuum tube type heat treatment furnace; mg-3Zn-2Cu; the Mg-3Zn-3Cu three alloy test bars were subjected to solution treatment for 24, 48, 60, and 72 hours (in the order of B, C, D, and E groups), and the cooling method was water cooling.
Referring to fig. 1-8, when Cu is added at a 2wt.% content, fine equiaxed grains may be formed. After the solution treatment, the granular MgZn phase disappears, the MgZnCu phase is partially dissolved, and the undissolved phase is decomposed into granules in the solution treatment process. The solubility of Cu in the Mg matrix at 430 ℃ is very low (about 0.31-0.55 wt%), so more MgZnCu phase will accumulate along or within the grains with more Cu addition, with a higher volume fraction of Cu, resulting in further improvement of conductivity. The cast Mg-3Zn alloy consists of an alpha-Mg matrix and an MgZn eutectic phase in a crystal boundary, the grain size of the alpha-Mg phase is reduced along with the addition of Cu (2 wt percent content), and the tensile strength, yield strength and elongation of the cast Mg-3Zn-2Cu alloy reach 230Mpa,103Mpa and 29.3 percent. After the solution treatment, the granular MgZn phase disappears, the MgZnCu phase is partially dissolved, and the undissolved phase is decomposed into granules in the solution treatment process. Under the conditions that the solid solution temperature is 430 ℃ and the solid solution time is 72h, the volume fraction of Cu element in the alloy is the highest, and the conductivity of the Mg-3Zn-2Cu alloy reaches 21.03 MS.m -1 . A comparison of tensile and electrical conductivity properties of Mg-3Zn-xCu (x =1,2, 3) alloys is seen in tables 1 and 2:
while the invention has been described in further detail with reference to specific preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
