However, neither study examined carbide size or the different hardness of MC and M 6 C carbides. Komanduri and Shaw studied the effect of powder metallurgy (PM) on grindability of T15 steel [7]. They found that, under plunge-grinding conditions, G-ratios for grinding of PM T15 were double those of conventionally produced (CONV) T15.
