A Critical Evaluation of the Factors Influencing High Strain Rate Superplasticity
Abstract
This Final Report lists the publications arising from this research program and also provides a brief description of the major findings. There were two major objectives of this program and both were fulfilled within the research period. These objectives were: (1) to obtain a detailed understanding of the creep properties of metal matrix composites which are important in the field of high strain rate superplasticity; and (2) to attempt to extend the range of materials exhibiting high strain rate superplasticity to commercial unreinforced alloys by using a new processing technique in which an ultrafine grain size is achieved by introducing severe plastic deformation. This latter objective has led to the first demonstration of superplasticity at very high strain rates and at relatively low temperatures in conventional materials.
