英文摘要	The mechanical properties and wear behavior of an Fe₇₀Ni₃₀ alloy with twinned martensite structure obtained by deep cryogenic treatment at −196 ℃ (DCT) were evaluated in comparison with that of coarsegrained (CG) Fe₇₀Ni₃₀ alloy (single austenite phase). The results showed that after the introduction of martensite with nano-scale twins, the Vickers hardness of Fe₇₀Ni₃₀ increased from 145 to 248 Hv. The friction coefficient of both samples was almost the same, and it decreased with increasing applied load and increased with increasing sliding speed. The XPS results indicated that oxide protecting film was formed on the worn surface, which may dominate the friction coefficient. The wear rate for both samples increased with increasing applied load and decreased slightly with increasing sliding speed. The wear resistance of DCT-Fe₇₀Ni₃₀ alloy was obviously enhanced. The wear mechanisms were investigated by SEM accordingly.
