Method for Producing Ultrafine-Grained Materials Using Repetitive Corrugation and Straightening

Abstract
A method of refining the grain structure and improving the hardness and strength properties of a metal or metal alloy workpiece is disclosed. The workpiece is subjected to forces that corrugate and then straighten the workpiece. These steps are repeated until an ultrafine-grained product having improved hardness and strength is produced.
