Laser Remelting Effect on the Joint Property of Diffusion Bonding of TiAl Intermetallics and TC4 Alloy

摘要：

　　The influence of laser remelting on the mechanical property and fracture behavior of the superplastic diffusion bonding between TiAl intermetallics and TC4 alloy was investigated.The joint bonded by the pre-remelted samples displayed well diffusion,but the mechanical properties of the joint should be further enhanced.The mechanical properties of the joint pre-remelted under the diffusion bonding conditions of 915℃/80MPa/1h are lower than that of the joint without remelting.After the heat treatment on pre-remelted joint sample at 860℃,the mechanical properties have been enhanced greatly.
