Orthogonal cutting experiments of Fe-36Ni invar alloy are performed to investigate the influence of cutting conditons on adiabtic shear, which occurs in the process of chip formation of many materials. It is found that the cutting speed, cutting depth and rake angle all have influence on adiabatic shear and there is a critical cutting speed at which the adiabatic shear appears.

The Fe‐rich portion of the system Fe‐Ni‐O‐S is a eutectic system with a wide region of liquid immiscibility which is reduced with increasing pressure and which disappears above 20–25 GPa. The oxygen solubility in the eutectic liquid increases with pressure, from 1 atomic percent at 6 GPa to about 2–3 atomic percent at 15 GPa.
