Summary
The fracture toughness and the fatigue-crack growth characteristics of M2 high-speed steel have been measured for a wide range of hardening and tempering temperatures. The effect of differing hardening treatments on the occurrence of chipping of the cutting edge during a severe, single-point, surface-milling operation has been compared with these toughness results. A qualitative explanation for the occurrence of this edge chipping has been suggested in terms of the critical flaw size and the primary carbide size and distribution.
