Description

The wear resistance and its mechanism in an Fe-17Mn-5Si-10Cr-4Ni shape memory alloy have been studied by means of friction wear tests, X-ray diffraction (XRD) and scanning electron microscopy (SEM). Results show that the wear resistance of Fe-17Mn-5Si-10Cr-4Ni alloy in oily friction is remarkably higher than that in dry friction. Compared with stainless steel, the wear resistance of Fe-17Mn-5Si-10Cr-4Ni alloy in dry friction is lower, but higher remarkably in oily friction. From XRD analysis and SEM observations, it is found that there are large amounts of ε martensite in the worn surface of Fe-17Mn-5Si-10Cr-4Ni alloy after oily friction, but no ε martensite in the worn surface of the alloy after dry friction. From these results, it is concluded that the mechanism for high wear resistance of Fe-Mn-Si shape memory alloy in oily friction is stress-induced γ → ε martensitic transformation
