摘要：
Transient liquid phase bonding of Incone1718 superalloy was carried out using a commercial Ni-Cr-Si-B amorphous interlayer. The interfacial microstructure of Incone1718 joints was analyzed by a scanning electron microscope and a transmission electron microscope. In particular, the effects of post-weld heat treatment on the interfacial microstructure and joining properties of Incone1718 joints were investigated in detail. The results showed that the precipitation of second phases in joints induced by post-weld heat treatment were beneficial to the improvement of joint properties. A tensile strength of 1130 MPa with an elongation percentage of 7% was achieved for a sample bonded at 1050 degrees C/60 min+1180 degrees C/60 min followed by the post-weld heat treatment.
