Abstract

Abstract : A cobalt-base alloy and an iron-base hardfacing alloy were characterized by in situ diffraction during tensile testing at room and elevated temperatures. Both alloys showed a transition temperature above which a stress-induced martensite transformation disappears. This transition temperature is high (700–825 °C) for the cobalt-base alloy and low (<350 °C) for the iron-base alloy. These values correlate with the temperatures above which wear resistance is reported to decrease in each alloy.
