Fatigue limit estimation for Ni-based alloy based on the dissipated energy measurement

Abstract

The fatigue limit estimation based on the dissipated energy measurement has been developed and the applicability of this technique for some steels has been investigated. However, there have been no reports on high-strength materials such as Ni-base high-strength alloys. Establishment of a simple and rapid fatigue limit estimation method for materials used under high load environment like this material is expected to greatly contribute to improvement of machine safety and reliability. In this study, we investigated the applicability of fatigue limit estimation method based on dissipated energy measurement for Ni-based alloy Inconel718.
