Abstract

The high temperature high cycle fatigue behaviour of a directionally solidified Co-base superalloy was investigated. The alloy has superior fatigue resistance at 900 °C and its fatigue strength is up to 295 MPa. Its σ-N_f curve is characterized by three distinct zones. The stronger dependence of N_f on σ in the high and low stress zones results from multiple fatigue crack initiation sites produced by high stress and oxidation effect in a prolonged exposure, respectively.
