Abstract:
Fe 70 Ni 30 alloy with nanoscale twins was obtained by deep cryogenic treatment (DCT) of coarse grained Fe 70 Ni 30 alloy (CG-Fe 70 Ni 30 ) at liquid nitrogen temperature. The tribological behavior of DCT-Fe 70 Ni 30 alloy was investigated under liquid paraffin oil lubrication compared with that of CG-Fe 70 Ni 30 alloy. The experimental results showed that the wear resistance of DCT-Fe 70 Ni 30 alloy was improved significantly after the introduction of nanoscale twins, and DCT-Fe 70 Ni 30 alloy also showed a little lower friction coefficient relative to CG-Fe 70 Ni 30 alloy. The results indicated that twins play a positive role in the material's friction-reduction and anti-wear properties, which is attributed to the better oil-adsorption ability and enhanced hardness of DCT-Fe 70 Ni 30 alloy caused by structural refinement. Wear mechanisms were discussed.
