The interdiffusion of couples of pure Cu and Cu-6.54 .or Cu-9.76at%Si alloy was studied by using electron probe micro-analytical techniques. It was found (table 105) that the activation energy at 0at%Si corresponded to that for Si diffusion in Cu. These were smaller than that for self-diffusion in Cu.
