摘要：
Experimental data is presented which compares the effect of grinding and high speed milling (HSM) on the fatigue strength of a gamma titanium aluminide intermetallic alloy. Results showed that HSM significantly increased fatigue strength by as much as 200 MPa over polished samples. Measurement and analysis of workpiece subsurface microhardness and microstructure indicated that the high run-out values correlated to high hardness and plastic deformation of the near surface lamellae.
