在金属和合金熔体中添加适当的晶粒细化剂,在铸造组织中可以获得微细的等轴晶组织,从而改进其性能。本文提供了通过添加促进非均匀形核的添加剂使铝和铜合金晶粒细化的研究结果。
Adding appropriate grain refiners to the metal and alloy melts results in fine equiaxed grain structures in the cast structure, improving its performance. This article provides the results of a study of grain refinement of aluminum and copper alloys by the addition of additives that promote inhomogeneous nucleation.
