摘要	The Mo-14Re/Inconel 625 alloy joint brazed using traditional BNi-2 or Cu interlayers generally exhibited unsatisfactory bonding strength and cracks due to a large mismatch of coefficient of thermal expansion (CTE) between the base materials. In this study, Mo-14Re and Inconel 625 were brazed using two routes: 1) One-step brazing with Au-Ni paste achieved a shear strength up to 547.9 MPa, due to the predominance of high-strength and ductile Au(s,s) in the brazed joint; 2) Two-step brazing with Ti-Zr-Cu-Ni filler and Nb interlayer, which regulated the formation of the brittle intermetallic compounds and residual stress, produced a crack-free brazed joint.
