摘要
采用喷射沉积工艺制备了Ａｌ５．５Ｃｕ／ＴｉＡｌ３自生复合材料，并对该材料的微观组织及界面结构进行了研究。观察表明ＴｉＡｌ３与αＡｌ基体之间存在（０２０）Ａｌ／／（００２）ＴｉＡｌ３，［００１］Ａｌ／／［１１０］ＴｉＡｌ３的位向关系，力学性能测试结果表明喷射沉积Ａｌ５．５Ｃｕ／ＴｉＡｌ３自生复合材料的抗拉强度较铸态的抗拉强度提高约１２％，延伸率提高４５０％，耐磨性则提高１５０％。
Al 5.5Cu/TiAl 3 in situ composites was produced by spray deposition, and the microstructure and interfacial structure of the materials were analyzed. The observation show that the orientation relationship between TiAl 3 and α Al is Al //0] TiAl 3 , (020) Al //(002) TiAl 3 . The mechanical properties of the materials were tested. The results show that the tensile strength of the materials produced by spray deposition is 112% of that produced by cast and the elongation is increased to 550%, and the wear resistance is increased to about 250%.
