For ferrous alloys, quench hardening is an austenite-forming (austenitizing) heat treatment, followed by
hardening rate (5). One quantitative measure of the work-hardening rate is the strain-hardening exponent, n. A high work-hardening rate enhances the formability of a sheet by allowing an area which thins prematurely to harden and thus become stronger than the surrounding material.Some results are removed in response to a notice of local law requirement.
