Inhomogeneity of Strained Grains in the Microstructure at Elevated Temperatures

We have plotted experimental curves of the distribution of microstrains and determined the characteristics of the stress-strain state of grains in a single-phase austenitic alloy ChS-68 at test temperatures of 20, 400, and 650 deg C. As the degree of deformation was increased from 6 to 40%, the microstrains increased and the curves of the distribution of the microstrain intensity at all the studied temperatures (20, 400, and 650 C) became flatter.
