Shape Memory Effect in Corrosion-Resistant Steels Hardened by Various Carbides

Resumo

The possibility of increasing the reversible deformation to 1.9% of corrosion-resistant steels 0.30C–14Cr–15Mn–4Si–3Ni–1V and 0.30C–14Cr–15Mn–4Si–3Ni,which exhibits the shape-memory effect has been shown. The increase has been achieved at the expense of a decrease in the chromium and carbon contents in an austenite matrix, which results from the decrease in the quenching temperature and increase in the time of destabilizing carbide aging.
