Elevation of Impact Toughness of Medium-Manganese Trip-Steel 0.2% C – 6% Mn – 3% Al Due to Evolution of Microstructure Under Heat Treatment

  • Published:
Metal Science and Heat Treatment Aims and scope

The possibility of raising the impact toughness of medium-manganese TRIP-steel Fe – 0.2% C – 6% Mn – 3% Al by application of a novel heat treatment involving quenching from the intercritical temperature range and subsequent tempering is investigated. Electron microscope and x-ray diffraction studies are performed after the heat treatment. The quenching mode providing the highest impact toughness is determined.
