The influence of cold rolling on diffusion bondability has been systematically investigated using SUS316L stainless steel sheets with different reduction ratios (0, 35, 50 and 70%) as specimens. According to the results of tensile testing of diffusion bonds, highly rolled sheets exhibit enhanced diffusion bondability. This phenomenon is discussed from the viewpoint of the microstructure.
