摘要

通过正交试验

对原位20Mg2Si/Al复合材料中的初生Mg2Si进行变质处理。结果表明

最佳的工艺参数是:P的加入量为0.03%

混合稀土的加入量为0.4%

变质温度为780℃

变质时间为30min。在影响变质效果的因素中

P的加入量对变质效果影响最大。混合稀土、变质温度和变质时间对试验有一定的影响。

Abstract

Through designing orthogonal experiment

modification treatments were performed on the primary Mg2Si phase in in-situ 20Mg2Si/Al composites.The results show that the optimized process parameter is presented as follows:0.03% P addition

0.4% mixed rare earth and the modification temperature of 780 ℃ as well as 30min of the modification time.The key influencing factors are P addition

and then mixed RE addition

modification temperature and modification time.
