Description
Summary:Experimental results for high-temperature deformation of an iron-based structural material in the temperature ranges including the points of the Fe sub alpha - > Fe sub beta - > Fe sub gamma transition are given. It is shown that the strain-strength properties of the material change nonmonotonically on the interval 700 deg C < T < 1000 deg C and that the internal phase-structural changes exert an effect on the thermal effects. Approximating dependences that permit one to describe deformation processes in the indicated temperature ranges upon uniaxial loading are proposed.
