preparation example Construction

[0023] The preparation of the wrought magnesium alloy of the present invention can adopt the currently commonly used magnesium alloy smelting process, wherein, the smelting process adopts the steps of existing material preparation→melting→refining→pouring, and each step of the preparation method of the wrought magnesium alloy of the present invention is now described The details are as follows:

[0024] Step 1, material preparation: 1) Raw materials: prepare pure magnesium ingots (purity ≥99.9wt%), pure aluminum ingots (purity ≥99.9 wt%), pure zinc ingots (purity ≥99.9 wt%), pure elemental cobalt (purity ≥ 99.9wt%) and aluminum-manganese master alloy ingots.

[0025] 2) Flux: The underflux, covering agent and refining agent can all use the existing underflux, covering agent and refining agent for magnesium alloy preparation, such as covering agent RJ-6 and refining agent RJ-5.

[0026] Step 2. Drying: Dry the prepared raw materials, wherein Mg, Al, Zn, and Co are dried at 100...

Embodiment 1

[0038] The preparation method of the wrought magnesium alloy of embodiment 1 of the present invention comprises the following steps:

[0039] 1. Drying: Dry the prepared raw materials: pure magnesium, pure aluminum, pure zinc (purity ≥ 99.9 wt%), pure cobalt and aluminum-manganese master alloy, among which Mg, Al, Zn, co Dry at 100°C, while the AlMn master alloy is baked at 150°C.

[0040] 2. Melting: During the whole melting process, continuously feed SF into the resistance crucible 6 Gas protection, first preheat the resistance crucible to 200 ° C, sprinkle an appropriate amount of refining agent RJ-5 and covering agent RJ-6 on the side wall and bottom of the crucible, and then put in the weighed Mg, Al, Zn metal ingots , continue heating, after the Mg, Al, and Zn metal ingots are all melted, add the weighed AlMn master alloy at a temperature of 680°C and sprinkle the covering agent RJ-6 evenly from time to time; after the AlMn master alloy is completely melted , then add...

Embodiment 2

[0042] The raw materials and preparation method are basically the same as those in Example 1, except that the amount of cobalt added is 0.35wt%, and the cast magnesium alloy rod B2 is obtained.

Abstract

The invention discloses a high-strength high-plasticity wrought magnesium alloy. The magnesium alloy comprises the following components in percentage by weight: 5.0-7.5 percent of Al, 0.40-1.20 percent of Zn, 0.05-0.50 percent of Mn, 0.05-1.0 percent of Co and the balance of Mg and inevitable impurities. According to the high-strength high-plasticity wrought magnesium alloy disclosed by the invention, the metal element Co is mainly added into an existing magnesium alloy smelting process, a stable and fine grain structure can be obtained by virtue of the action of the metal element Co, the strength and the room temperature plasticity are greatly improved, and the room temperature processing or using requirements on finished products or semi-finished products can be met.

Description

technical field [0001] The invention relates to the technical field of magnesium alloy materials, in particular to a deformed magnesium alloy with high strength and high plasticity. It belongs to the field of metal materials. Background technique [0002] Magnesium and magnesium alloys are lightweight materials in the 21st century. Magnesium alloys have light specific gravity, high specific strength and specific stiffness, good damping, thermal conductivity, machinability and castability, and also have strong electromagnetic shielding ability and rich resources. With a series of advantages such as easy recycling and easy recycling, its development and application have received more and more attention, and it has become one of the "youngest" metal structural materials. It is applied to structural parts in aerospace, automobile, transportation and other fields, which can significantly reduce weight and save fuel consumption. [0003] Deformed magnesium alloys refer to magnes...
