Abstract

A process is described for removing the detrimental effects of residual stresses in cold-rolled alloys without heat treatment. The process consists of reverse bending the strip over a small diameter cylinder such that the plastic tensile strain at the outer fibers exceeds several percent. The bending yield strength of an AISI Type 301 stainless steel was increased over 80% by the procedure. Subsequent low temperature heat treatments resulted in further improvements.
