Hard alloys count among the hard‐to‐machine materials. Performance characteristics such as high hardness and wear resistance as well as the structural difference between hard phases and metallic matrix impede their machineability. The authors review the effects of the mechanical and thermal energy exerted by turning and grinding processes on the materials surfaces. Since high thermal surface loading may cause crack formation in hard phases as well as hardness increase and softening in the case of iron‐based alloys they recommend to always take surface area requirements into account.
