看了几篇文献对于合金的制备描述都是这样的：
Starting Al-Cu alloys with nominal compositions of 15, 20, 25, 30 and 35 at.% Cu were prepared from Al and Cu with purity of 99.9 wt.%
Mg–Cu–Pd alloys with nominal compositions of Mg50Cu45Pd5 and Mg50Cu40Pd10 (at.%) were prepared from pure elements (purity: 99.9 wt. %) in a quartz crucible using a high frequency induction furnace in an argon atmosphere.
想知道这种制备方法的具体操作是什么，使用
金属粉末还是用块状金属?直接用炉子加热熔融即可吗？温度怎么设定？升温速率是否有要求？
