Microstructure and Properties of Vacuum Diffusion Bonded CLAM Steel Joint

In this study,CLAM steel was welded by vacuum diffusion bonding.The microstructures of the joints bonded under different temperatures and holding times were investigated.The mechanical properties of the joints were characterized by shear strength tests.The results indicate that the vacuum diffusion bonding can realize the reliable joining of CLAM under the appropriate bonding temperature and holding time(bonding ratio not less than 90%).The shear strength of joints may be as high as 648 MPa.
