铝合金细化剂细化行为研究现状与展望
Research Status and Prospect of Refining Behavior of Aluminum Alloy Refiners
摘要
Abstract
Grain refinement of aluminum alloys can significantly improve their overall performance,which is significant for expanding their applications.Based on the heterogeneous shape nuclei,this paper discussed the dot mismatch model,the edge matching model and the free growth model,and confirmed the efficiency of the edge matching model in screening potential grain refiners.According to theoretical study of the effect of the free growth model on the size,morphology and distribution of heterogeneous phases on the grain refinement effect,the research progress of physical and chemical methods to regulate the second phase and thus optimize the refinement effect was summarized,and the reason why the second phase size affects the refinement effect was theoretically discussed.Finally,the direction of optimizing the grain refinement agent was discussed.关键词
