Method for enhancing superplasticity in composites

摘要

A method for inducing superplasticity in a composite including a non- transforming phase and a transforming phase by cycling the composite material through a phase transformation of the transforming phase while applying an external stress to the composite material is provided as is a method for inducing superplasticity in a titanium/titanium carbide composite. Also provided is a method for forming a part from a composite material including a transforming phase and a non-transforming phase by cycling the composite through a phase transformation of the transforming phase and shaping the composite material by applying an external stress to the composite material while the transforming phase is undergoing a phase transformation to form a finished article.
