Abstract
Severe plastic deformation in an eutectic tin-lead alloy is studied by impo sing fast bending at room temperature, in an attempt to examine the microst ructural response in the absence of thermally activated diffusion processes . A change in microstructure due to this purely mechanically imposed load i s observed: the tin-rich matrix phase appears to be extruded out of the nar row region between neighboring layers of the lead-rich phase and alteration s in the colony structure occur. A micromechanism is proposed to rationaliz e the experimental observations. (C) 2001 Elsevier Science B.V. All rights reserved.
