HOT DEFORMATION INHOMOGENEITY OF AUSTENITIC STEEL

Abstract
Using the installation of high-metallography, the irregularity of deformation of steel 08Cr18Ni10Ti with the content – 28 % of ferrite has been investigated. It has been established that the average amount of ferrite deformation is greater than the austenite one; and this difference increases with the temperature rise. With the temperature rise increases the slippage on interphase boundaries. The ratio of hot microhardness of δ-ferrite to austenite decreases with the increase of test temperature.
