Varestraint Weldability Testing of ATI 718Plus (R)-Influence of Eta Phase
Paper i proceeding, 2018

This study investigates the effect of eta phase on hot cracking susceptibility of ATI 718Plus (R). Two heat treatment conditions of 950 degrees C/1 h and 950 degrees C/15 h having different amounts of eta phase were tested by longitudinal Varestraint testing method. The heat treatment at 950 degrees C/15 h exhibited the highest amount of cracking. This was related to the higher amount of eta phase precipitation during the long dwell heat treatment which aided to extensive liquation during welding.
