Abstract

Tensile strength of diffusion welded joint of aluminum matrix composite is very low due to its poor weldability. Solution and age treatments were conducted on the welded joint of Al₂O_3P/6061Al composite subjected to diffusion welding using Gleeble 1500 machine, and tensile strength and microstructure of welded joint aged at 175°C were measured and analyzed respectively. Results showed that aging precipitation of welded joint is promoted effectively because of redistribution of reinforcement and a few number of dislocations in the matrix of weld zone resulting from welding pressure, and hence tensile strength of welded joint is increased significantly after aging treatment.
