摘 要：采用喷射沉积工艺制备了Al-5.5Cu/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α-Al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Al-5.5Cu/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%。
Abstract: Al-5.5Cu/TiAl3 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 TiAl3 and α-Al is [001]Al//[1-10]TiAl3, (020)Al//(002)TiAl3. 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 isincreased to 550%, and the wear resistance is increased to about 250%.
