Description
Technical Field
The invention belongs to the technical field of nonferrous metal solid solution strengthening processing, 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 the as-cast state is 19.06-20.34 MS.m -1 Between which are locatedAnd has great application potential under high temperature condition, and plays an important role in the application of 5G base stations and the field of mobile phones. However, with the continuous development of the electronic industry, a magnesium alloy with high conductivity is required to meet the strict requirements by keeping the device temperature within a safe range and extending the service life of electronic products.
The conductivity of Mg-Zn alloys decreases with increasing content of alloying elements. This phenomenon is mainly caused by alloy atoms dissolved in the magnesium matrix. The size of solute atoms is different from that of magnesium atoms, so that the lattice of the magnesium alloy is distorted, and finally the thermal conductivity is reduced.
In Mg-Zn alloys, the precipitated phase during the solution process is formed by the aggregation of Zn atoms, and at intermediate temperatures (about 100 ℃) solution treatment, many different types of precipitates exist simultaneously, resulting in hardening of the alloy while improving the electrical conductivity of the alloy. The heat treatment sequence of the alloy is reported to be SSSS→pre-beta ‘ →β 1 ‘ (rod-like and block-like precipitates {0001} Mg, mg 4 Zn 7 ）→β 2 ‘ (mainly coarse particles {0001} Mg and some lath-like precipitates {0001} Mg, mgZn) 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 it can make solid solution treatment at higher temperature to make more Zn and Cu solid solution. Although researchers have made intensive studies on Mg-Zn-Cu-based magnesium alloys, the relationship between the conductivity after solution treatment and the structure evolution after solution treatment of Mg-Zn-Cu-based magnesium alloys has not been elucidated.

When Cu is added in an amount of 2wt.%, fine equiaxed grains can be formed. After 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 Mg matrix is very low (about 0.31-0.55 wt%) at 430 c, so that more MgZnCu phase accumulates along or within the grains with more Cu addition, and the volume fraction of Cu is higher, further improving conductivity.
2.

Example 1
Step 1, designing alloy components: in the embodiment, three groups of Mg-Zn-Cu magnesium alloys are designed by taking magnesium blocks, zinc blocks and copper wires as raw materials, and the specific tables are as follows:
step 2, alloy smelting
In this example, an alloy system was prepared using a box-type resistance furnace under the condition of a protective gas (argon). The specific table is as follows:
1) Molten magnesium ingot
When the temperature of the resistance furnace is raised to 500 ℃, a preheated (200 ℃) magnesium block is added into a crucible, a dried covering agent is spread on the magnesium block, and high-purity argon is introduced into a box-type resistance furnace to carry out gas protection (magnesium is a very active metal element and is easy to be mixed with O in the air at high temperature) 2 And water vapor reaction, affecting alloy properties);when the temperature of the resistance furnace is raised to 720 ℃, the temperature is kept for 20 minutes at a constant temperature, so that the magnesium blocks can be completely melted.
2) Zinc and copper additions
After the magnesium block is completely melted, the furnace cover is opened to clean the surface of the solution by a slag skimming rod, then the preheated zinc block is added, and the furnace cover is closed to start heating after the dried covering agent is spread. When the temperature is increased to 750 ℃, a slag skimming rod is used for cleaning the surface of the solution after secondary furnace opening, preheated copper wires are added according to the test requirement, the covering agent is scattered after stirring, a furnace cover is closed, and the temperature is kept for 5 min.
3) Refining

Finally, after uniformly spreading the covering agent, closing the furnace cover, and preserving heat for 20 min after the furnace temperature is raised to 750 ℃.
4) Pouring
After heat preservation for 20 min at 750 ℃, the furnace temperature is reduced to 740 ℃, and after the surface of the solution is cleaned by a slag skimming rod, the magnesium alloy melt is cast into a preheated mould (200 ℃). And after the temperature of the die naturally cools to room temperature, taking out the sample from the die to obtain the as-cast alloy test bar.
Step 3, solution treatment
Respectively carrying out Mg-3Zn-1Cu on three groups of alloys; mg-3Zn-2Cu; and carrying out solid solution treatment on the Mg-3Zn-3 Cu. Before solution treatment, cast Mg-3Zn-1Cu; mg-3Zn-2Cu; samples of Mg-3Zn-3Cu alloy (group A) were subjected to differential thermal analysis. The DSC curve of the alloy shows an endothermic peak, and 470 ℃ corresponds to the endothermic peak of the second phase of the alloy. Therefore, in order to avoid the second phase overburning in the alloy, the solution temperature of the alloy was set to 430 ℃. Then, respectively carrying out heat treatment on the as-cast Mg-3Zn-1Cu by using a vacuum tube type heat treatment furnace; mg-3Zn-2Cu; the three alloy test bars of Mg-3Zn-3Cu are subjected to solution treatment for 24, 48, 60 and 72 hours (B, C, D, E groups in sequence), and the cooling mode is water cooling.

After solution treatment, the granular MgZn phase disappears, the MgZnCu phase is partially dissolved, and the undissolved phase is in solid solutionDuring the treatment, the particles are decomposed. The solubility of Cu in Mg matrix is very low (about 0.31-0.55 wt%) at 430 c, so that more MgZnCu phase accumulates along or within the grains with more Cu addition, and the volume fraction of Cu is higher, further improving conductivity. The as-cast Mg-3Zn alloy consists of an alpha-Mg matrix and MgZn eutectic phase in a grain boundary, the grain size of the alpha-Mg phase is reduced along with the addition of Cu (2 wt.% content), and the tensile strength, the yield strength and the elongation of the as-cast Mg-3Zn-2Cu alloy reach 230mpa,103mpa and 29.3%. 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 of the solid solution temperature of 430 ℃ and the solid solution time of 72 hours, the volume fraction of Cu element in the alloy is highest, and the conductivity of the Mg-3Zn-2Cu alloy reaches 21.03 MS m -1 . Comparison of tensile properties and electrical conductivity properties of Mg-3Zn-xCu (x=1, 2, 3) alloys is seen in tables 1 and 2:
