Basic Guide to Cutting Tool Materials (How to Choose?) - MachineMfg

The grain size of ultra-fine grain alloys is 0.2~1μm, most of which are below 0.5μm. In the fine-grained alloy, the hard phase and the bonding phase are highly dispersed, which increases the bonding area and improves the bonding strength. Therefore, its hardness and strength are higher than alloys of the same composition.
