abstract = "The effect of in situ reaction on the properties of pulsed Nd:YAG laser welded joints of particle reinforcement aluminum matrix composite SiCp/A356 with Ti filler was studied, and its corresponding temperature field was simulated. Results shows that in situ reaction during the laser welding restrains the pernicious Al4C3 forming in the welded joints effectively. At the same time, the in situ formed TiC phase distributes uniformly in the weld, and the tensile strength of welded joints is improved distinctly. Furthermore simulation results illustrate that in addition to the lower heat-input into the substrate because of Ti melting, in situ reaction as an endothermic reaction decreases the heat-input further, and its temperature field distributes more smoothly with in situ reaction than that of laser welding directly. Also, the succedent fatigue test shows the antifatigue property of welded joints with in situ reaction is superior to that of traditional laser welding. It demonstrates that particle reinforcement aluminum matrix composite SiCp/A356 was successfully welded by pulsed Nd:YAG laser with in situ reaction. {\textcopyright} 2011 Nova Science Publishers, Inc.",
