Abstract

Spenningsherdede stållegeringer med en høy strekkfasthet er behandlet ved kaldbearbeiding av legeringer, hvis mikrostruktur omfatter korn i hvilke martensittgitter alternerer ved tynne filmer av stabilisert austenitt. Grunnet høy dislokasjonstetthet i denne mikrostrukturen og en tendens for spenninger til å bevege seg mellom martensitt- og austenittfasene, vil spenningene dannet ved kaldbearbeiding tilveiebringe mikrostrukturen med unike mekaniske egenskaper omfattende en høy strekkfasthet.Dette er overraskende oppnådd uten behov for mellomliggende varmebehandlinger (patentering i tilfelle ståltråd) av stålet mellom reduseringene ved kaldbearbeiding.Stress-hardened steel alloys with a high tensile strength are treated by cold working of alloys, the microstructure of which comprises grains in which martensite lattice alternates with thin films of stabilized austenite. Due to the high dislocation density of this microstructure and the tendency of stresses to move between the martensite and austenite phases, the stresses formed by cold working will provide the microstructure with unique mechanical properties including a high tensile strength. steel wire) of the steel between the reductions during cold working.
