Abstract

The effect of the elastic incompatibility on the deformation of α-β brass two-phase bicrystals was studied at temperatures of 150, 300 and 450 K. At 150 and 300 K, the curvature of the slip traces in the β-component with distance from the interface was found to be closely related to the exponential decay of the elastic incompatible stresses with distance from the interface. More than four slip systems (which are necessary for the plastic compatibility theory) were observed to operate and although the total number of slip systems differed from one specimen to another, it can be rigidly concluded that additional slip systems have been activated due to the elastic compatibility requirements.
