ABSTRACT:
A duplex rolling process and apparatus for working a metal or alloy subject to the formation of strain induced martensite. The metal or alloy is first worked at an elevated temperature wherein the formation of strain induced martensite is substantially suppressed or eliminated. The metal or alloy is then worked at a lower temperature wherein the formation of strain induced martensite is promoted whereby working is carried out more efficiently.
