- 摘要:
- 以 15%Mg 的铜镁合金为原料，在真空感应炉中用不同压强制备 1%Mg 的铜镁合金，研究了压强对铜镁合
金镁成分的影响。结果表明，铜镁合金制备中镁元素易烧损，在较低压强下能降低镁元素的烧损。压强在 1 000 Pa 时，镁
含量可以控制在 0.76%，烧损率为 24%。
The 1%Mg copper-magnesium alloy was prepared with 15%Mg copper-magnesium alloy as raw material at different pressures in a vacuum induction furnace. The results show that the burning loss of magnesium in the preparation of copper-magnesium alloy is easy, and the burning loss of magnesium can be reduced at lower pressure. When the pressure is 1 000 Pa, the magnesium content can be controlled at 0.76% and the burning loss rate is 24%.
