摘要

The processes of equal-channel angular pressing (ECAP) and high-pressure torsion (HPT) are now established for the fabrication of ultrafine-grained metals having superior properties by comparison with their coarse-grained counterparts. This article examines the recent developments designed to improve the processing technology of ECAP and HPT and to establish these techniques as viable procedures for use in industrial applications. Based on these developments, it is reasonable to anticipate these processing procedures will experience increasing use in the fabrication of commercial products.
