Abstract

Low-carbon martensitic steels (LMS) susceptible to inheritance of structure are considered. The strength, ductility, toughness characteristics, fracture energy, grain structure of the austenite, and micro- and fine structures of heat treated LMS are studied. The formation and decomposition of the austenite is investigated by the method of differential scanning calorimetry (DSC). True strain diagrams and models are designed. Expressions relating the stresses and strains in the stages of uniform and lumped deformation are suggested, and the power criteria for tension and fraction of the LMS are computed.
