Fatigue crack growth behaviour of Inconel 718 with high temperature hold times
Paper i proceeding, 2010

In this work, fatigue crack growth measurements have been made on center-cracked tension specimens of Inconel 718, where the focus has been to observe the effect of high temperature hold times on the fatigue crack growth behaviour of the material. The material testing has been done at three different temperatures, namely 450 °C, 550 °C and 650 °C. All testing were done in an isothermal LCF context with a standard test method for measuring the fatigue crack growth rates. © 2010 Published by Elsevier Ltd.
