Abstract
A possibility of obtaining the shape memory effect has been investigated as a result of γ→e→γ transformations in stainless steels hardened by VC carbides. Age hardening conditions at 650 and 720 °C for stainless steels containing (in mass %) 0.20 – 0.35 C, 1 V, 3 – 4 Si, 9 and 13 – 14 Cr are presented. The values of reversible strain e determined after heating to 400 °C in specimens preliminarily deformed by 3.5 – 4 % vary from 0.15 to 2.7 % depending on the composition of the steels and the conditions of stabilizing and destabilizing aging.
