Conventional surface grinding was carried out on a horizontal–spindle (peripheral) surface grinder under indus-trial–use cutting conditions.
Wear loss values were measured by TG328B balance with 0.1 mg sensitivity repeated at least three times, and the worn surface was observed by S-4800N SEM to analyze the wear behavior and mechanism. Characteristics of the subsurface on the cross-section wear test specimens were also investigated using microstructural investigation.

Abstract The mechanical and wear behavior of a series of as-cast gray iron alloys were compared with properties obtained after austempering at 360 °C. The austempered alloys showed equivalent or moderately enhanced mechanical strength than the as-cast pearlitic gray irons. The specific wear rates of all the austempered alloys decreased significantly by 7–15 times and friction coefficient ...
