A major requirement of cutting tool materials used for machining aero-engine alloys is that they must possess adequate hot hardness to withstand the elevated temperatures generated at high speed conditions of aerospace alloys. Most cutting tool materials lose their hardness at elevated temperatures resulting in the weakening of the interparticle bond strength and consequent acceleration of tool wear which results in deterioration of surface roughness.
