Abstract

Mechanical properties of steel with a carbon content of 0.56 and 0.81% in tension at 800 and 1100°C are presented. It is shown that the strength of medium-carbon steel at austenitizing temperatures is higher than that of high-carbon steel. The method of computer modeling is used to determine the stress of uniform and localized deformation of austenite steel depending on the carbon content and the test temperature and on this basis the obtained experimental results are explained.
