本文给出了β相Cu基合金在固溶化处理和轧制过程中,B和B+Ti孕育对试样晶粒生长的后作用的研究结果.根据相应试样的断裂性能、断口形貌和含B析出物的分析,探讨了它们的后作用机理.最后,提出了获得优质Cu ZnAl形状记忆合金材料的最佳工艺. In this paper, we present the results of the study on the post-grain growth effects of B and B + Ti during the solution treatment and rolling of β-phase Cu-based alloys.Based on the fracture properties, fracture morphology and B precipitates were analyzed and their post-action mechanisms were discussed.Finally, the best process for obtaining high quality Cu ZnAl shape memory alloy materials was proposed.
