Effects of Temperature on the Weldability of Powder Metal Parts Joined by Diffusion Welding
Diffusion welding is an advanced bonding process in which similar or dissimilar materials can be bonded in solid state. In this study, aluminium composite (5% and 15% WC) powders were compacted at 450 MPa pressure and sintered at 550 oC for 45 minutes in argon atmosphere.and joined each other by diffusion bonding. The bonding temperatures (585 oC, 600 oC, 615 oC) and dwell time (185 min) were chosen for the welding process at constant 20 MPa. It has been observed that these variations on the welding parameter strongly affected the microstructure and the weldability of the materials.
