In situ X-ray diffraction analysis of strain-induced transformations in Fe- and Co-base hardfacing alloys

In situ X-ray diffraction analysis of strain-induced transformations in Fe- and Co-base hardfacing alloys

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...

Zusammenfassung: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 (
