Investigating Diffusion Bonded Joints of Some Heterogeneous Metals by Micro-Radiospectrophy (Issledovanie Diffuzionn'ikh soedinenii Nekotor'ikh Raznorodn'ikh Metallov Metodom Mikrorenttenospektral'nogo Analiza)

摘要

The diffusion welding of Cu and Mo, Cu and Steel, Cu and Ni, Ti and Ni, and Mo and Steel was investigated under several experimental parameters. The results of bonding were examined with metallography, x-rays, and microhardness tests. A Matano Analysis was applied to the concentration profiles to obtain diffusion coefficients in the weld zone. The role of various diffusion processes occurring during solid state welding was discussed.
