Abstract: Alexander Evgenievich Gvozdev studied a fundamental scientific direction of applied importance related to the development of the theory of superplasticity of metal alloys during phase transformations and its application for the production of cutting tool blanks from powder high-speed steel. Based on the proposed integrated approach, he revealed the nature of extreme effects and causes of changes in strength and plasticity in heterophase metal systems of traditional metallurgical processing and powder production method with different dispersion of carbide phases, forging alloys based on aluminum, copper-zinc metal alloy, etc. under thermomechanical influences and in pre-transition states before phase transformations of the I and II kind.

Keywords: superplasticity, phase transformations, plasticity, deformation resistance, high-speed steels, temperature-velocity parameters, current state.
