Abstract

The aim of this study was to develop a high-efficiency joining method of C_f/Al composites and TiAl alloys under the heat effect of laser-ignited self-propagating high-temperature synthesis (SHS). The SHS reaction of Ni–Al–Zr interlayer was induced by laser beam and acted as local high-temperature heat source during the joining. Sound joint was obtained and verified the feasibility of this joining method. Effect of filler metals on the joint microstructure and shear strength was evaluated. When the joining pressure was 2 MPa with additive filler metals, joint shear strength reached the maximum of 41.01 MPa.
