Ultradispersion microstructure and phase composition formation during intensive metal forming

Abstract

It was shown in this paper how rate, speed and temperature of forming influence on core size, as well as influence of the cooling speed on phase composition of construction steels. Different ways of intensive deformation achievement during metal forming and in particular a flat shaped condition: equal channel angular extrusion, drawing, cross-rolling, are considered in this paper. It should be also noted that for the receipt of the required structure and mechanical properties of steel apart from the use of rational speed-temperature process parameters of forming a metal damage limit should be taken into account.
