Effects of B_4C Addition on the Laser Beam Welding Characteristics of Al/SiC MMCs Produced By P/M
Abstract :
Fusion weldability characteristics of metal matrix composites (MMC) produced by powder metallurgy (P/M) are usually insufficient due to unwanted micro-structural changes that occur during welding. This study aims to investigate the effects of B_4C addition as reinforcement on the weld quality of Al/SiC MMCs. After the production of Al/SiC MMCs by P/M with or without the addition of B_4C, laser beam welding (LBW) characteristics of the materials were investigated by focusing on the integrity of the welds. Optical microscopy (OM), scanning electron microscopy (SEM), and energy dispersive X-ray analysis (EDX) were utilized for the characterization of the welds. Results show that Al/SiC MMCs produced by P/M can not be easily welded by LBW, but weldability characteristics of the material can be improved by the addition of B_4C.
