Abstract : The objective of the study was to determine the possibility of increasing heat resistance by means of thermomechanical processing of steels with manganous austenite. The test material was chromium-manganese-nickel steel, additionally alloyed with boron. This steel, E1711, is used in the construction of electric furnaces in place of chromium-nickel austenitic steel for parts operating at temperatures up to 700C. It is shown that low-temperature thermomechanical processing greatly increases the tensile strength of steel during short-term tests as a result of formation of a metastable state; the effect of an increase in the strength characteristics is not thermally stable and decreases with an increase in test time.
