Влияние холодной прокатки на закономерности и механизмы деформации, структурно-фазовые превращения и механические свойства монокристаллов стали Fe-28Mn-2.6Al-1.3C

Abstract

The dependence of microhardness of Fe-28Mn-2.6Al-1.3C single crystals on the degree of precipitation and deformation temperature is established. It can be divided into three sections: in sections I and III, the microhardness is slightly dependent on the orientation of the sample, while in section II the orientation dependence of microhardness is manifested. The orientation dependence of the microhardness is determined by the orientation dependence of the dislocation structure and the deformation mechanism (slip and / or twinning). Rolling does not lead to the realization of deformation phase transitions of steel Fe-28Mn-2.6Al-1.3C.
