Developments in Processing by Severe Plastic Deformation at the 3rd Pan American Materials Congress

The 3rd Pan American Materials Congress in San Diego, California, February 26–March 2, 2017, provided an opportunity to bring together many participants working in the field of severe plastic deformation. This article provides a brief review of these activities.

Principles of superplasticity in ultrafine-grained materials

Ultrafine-grained materials are attractive for achieving superplastic elongations provided the grains are reasonably stable at elevated temperatures. Since the strain rate in superplasticity varies inversely with the grain size raised to a power of two, a reduction in grain size to the submicrometer level leads to the occurrence of superplastic flow within the region of high strain ...
