Abstract

The material behavior of three Ni-base superalloys (Inconel® 718, Allvac® 718Plus™ and Haynes® 282®) during cyclic thermo-mechanical loading was investigated. Stress controlled thermo-mechanical tests were carried out at temperatures above 700 °C and different levels of maximum compressive stress using a Gleeble® 3800 testing system. Numerical precipitation kinetics simulations were performed using the software package
