Abstract
The paper presents the research results of the heterogeneity of hot
plastic deformation of 08Cr21Ni5Ti steel. Extension of samples was
carried out in the vacuum chamber of a testing machine IMASh-20-75 “Ala-Too”. To test the sample it was mounted in the vacuum chamber to the grippers with the help of bars. The junction of platinum – platinum-rhodium couple was welded to the side surface of the sample. The evacuation of air from the chamber was carried out up to a residual pressure of 5·10–5 mm Mercury (6.7·10–3 Pa). Heating of the sample up to 800 – 1200 °C was achieved by the heat from the current of industrial frequency transmitted through it. Accuracy of temperature regulation was ± 5 °C. The deformation of austenitic and ferritic phases was examined in dependence on the total degree of deformation of steel and temperature, the data about the infl uence of these factors on the intensity of slip at the interphase boundaries were also considered. The effect of the temperature on the ratio of hot microhardness of austenite and ferrite in 08Cr21Ni5Ti steel was investigated.
