摘要：

Two thick-wall parts of TA15 alloy were formed by laser rapid forming (LRF) process using unidirectional scanning pattern and weaving scanning pattern, respectively. The investigation on the effect of scanning pattern and heat treatment on the microstructures and the tensile properties of the LRFed TA15 alloy was carried out. Results show that the LRFed TA15 alloy has a good thermal stability of metallographic microstructures. The tensile properties of TA15 alloy formed by the weaving scanning pattern are superior to that of TA15 alloy fabricated by the undirectional scanning pattern due to finer metallographic microstructures of TA15 alloy obtained by the weaving scanning pattern. The tensile properties of as-deposited and heat-treated TA15 alloy prepared by the both scanning patterns are anisotropic, after the heat treatment of 940 degrees C/1 h/AC, the tensile properties of the formed TA15 alloy are better than that of the wrought annealed TA15 alloy.
