    Abstract

    The principles of equal-channel angular (ECA) pressing are reviewed. It is demonstrated that this processing procedure is capable of introducing an ultrafine grain size into bulk materials and the precise nature of the microstructure is dependent upon the total strain introduced by the pressing. When the strain is sufficiently high, it is possible to achieve very high tensile ductilities at high strain rates, thereby providing the potential for substantially increasing the viability of superplastic forming in the metal forming industry.
