FOERFARANDE FOER UTVIDGNING AV HYSTERESISSLINGAN HOS EN METALLBLANDNING MED REVERSIBEL FOERAENDRING MELLAN AUSTENITISKT OC MARTENSITISKT TILLSTAOND

摘要

Certain metallic compositions undergo a reversible transformation between an austenitic state and a martensitic state. The temperature at which these compositions begin to undergo the transition from martensite to austenite can be raised by deforming an article formed from the composition and maintaining it while in the deformed state at a temperature at which the composition would normally exist in the austenitic state.
