根据平衡理论,铅中含Al 4%的固溶体是不能存在的,因此用普通方法是不能制出含Al 4%铅合金。可是,Battele Columbus研究所用急速冷凝法和机械合金化法的联合法
According to the equilibrium theory, the solid solution containing 4% Al in lead can not exist. Therefore, Al 4% lead alloy can not be produced by ordinary methods. However, the Battele Columbus Institute uses a combination of rapid condensation and mechanical alloying
