Tempering Process

The wear behaviour of AISI 431 stainless steel was examined under a dry sliding touch at compatible load with the vacuum tempering cycle. The method adopted was found to be effective in enhancing the wear conduct of stainless steel products, there by advancing the pliability quality. For the sample, vacuum tempering (VT) procedure for (VT1) 2 hours, (VT2) 4 hours and (VT3) 6 hours respectively, a low temperature heat procedure was performed. Untreated stainless steel was used as a kind of viewpoint tool for contrast with specific hardening samples and observed wear check. The hardening samples expose those moulded hard layers which improve the hardness of the surface. Predictions of small scale hardness showed a significant change in hardness during diagnosis. This operation improves the hardness of the material to up to 150 percent. For wear inspection, a pin on the disc drive is used to assess wear failure. The layers were observed by optical lens magnification and examination under electron magnifying lens.

Transformation Behavior

Friction and wear performance of austenite stainless steels have been extensively studied and show a close relationship with the friction-induced martensitic transformation. However, how the grain size and associated friction-induced martensitic transformation behavior affect the tribological properties of austenite steels have not been systematically studied. In this work, dry sliding tests were performed on an AISI 304 stainless steel with a grain size ranging from 25 to 92 μm. The friction-induced surface morphology and microstructure evolution were characterized. Friction-induced martensitic transformation behavior, including martensite nucleation, martensite growth and martensite variant selection and its effect on the friction and wear behavior of the 304 stainless steel were analyzed. The results showed that both the surface coefficient of friction (COF) and the wear rate increase with the grain size. The COF was reduced three times and wear rate was reduced by 30% as the grain size decreased from 92 to 25 μm. A possible mechanism is proposed to account for the effect of grain size on the tribological behavior. It is discussed that austenite steel with refined grain size tends to suppress the amount of friction-induced martensitic transformed and significantly alleviates both the plowing and adhesive effect during dry sliding.
