EXPERIMENTAL DETERMINATION OF STRAIN HARDENING EXPONENT FOR STRENX 700

Abstract

During certain technological processes of production of parts and exploitation in extreme conditions like high temperatures, knowing the behavior of the material and its mechanical characteristics in these conditions is necessary. For ductile materials, reduction in strength and additional increases ductility are coming with increasing temperature. This behavior of the materials is the result of the influence of the temperature on its deformation. In order to determine the characteristics of the material in this case, it is necessary to perform material testing at elevated temperatures In this paper, material characteristic of high strength steel STRENX 700 was studied experimentally at elevated temperature.
