主　　题：laser beam welding SiC_p joint interfacial 

摘      要：The laser beam welding technique was used to process SiCparticles/6063Al alloy matrix composite, the in- fluence of laserpower and welding speed on the properties of joint was *** the laser beam power with same welding speed can make thequantity and size of Al_4C_3 decreased, and the ineractive mechanismof the reinforcing particles and the matrix in the joint and thecauses for joint strength reduction were analyzed. Increasing weldingspeed properly can improve the distribution of energy and restrainthe interfacial reaction in the molten pool, an measures for impovingwere proposed.
