Influence of machining conditions on tensile stress and ductility of a mechanically alloyed Fe–40Al intermetallic

The influence of a variety of machining conditions on the tensile behaviour of a mechanically alloyed FeAl intermetallic has been examined. Yield behaviour is hardly affected by machining conditions, and ductility is only weakly sensitive to machining speed or cutting depth. This behaviour seems to be related more with the extent of subsurface damage or work hardening than with the roughness of the machined samples. © 2002 Acta Materialia Inc.
