Abstract

THIS WORK AIMS TO STUDY THE INFLUENCE OF DEFORMATION TEMPERATURE AND STRAIN APPLIED ON THE REVERSE STRAIN INDUCED MARTENSITE TRANSFORMATION (RSIMT) OF FERRITE INTO AUSTENITE IN A SUPERDUPLEX STAINLESS STEEL. IT WAS FOUND THAT INCREASING APPLIED PLASTIC STRAIN LEADS TO REDUCTION OF THE FERRITE CONTENT WITHOUT FORMATION OF OTHER PHASES THAN AUSTENITE, WHICH CORROBORATES THE RSIMT HYPOTHESIS. HOWEVER, THE CRYOGENIC ROLLING TEMPERATURE DID NOT AFFECT THE PHASE TRANSFORMATION, WHICH OCCURRED IN THE SAME MANNER AS THE ROLLING AT AMBIENT TEMPERATURE.
