EFFECT OF LOW-TEMPERATURE PROCESSING ON PROPERTIES OF STEEL WITH MANGANOUS AUSTENITE (Vliyanie Nizkotemperaturnoi Obrabotk: Na Svoistva Stali s Marganstovistym Austenitom),
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.
