Abstract:

The scientific hypothesis of this work is that microstructure when acted upon by load and environment determines the fatigue-crack growth rates or life of a component. The experimental approach varied the heat treatment of two precipitation hardening martensitic alloys, 17-4 PH and 15-5 PH. Fatigue-crack growth data was correlated between materials cycled under wave forms of 10 Hz sine frequency and trapezoidal one minute hold-time for different stress range ratios and environments.
