Introduction The authors have discussed low cycle fatigue lives and cyclic constitutive relations of Mar-M247LC directionally solidified (DS) superalloy in the previous paper The solidification direction of crystals in DS plates is close to [001] crystallographic axis but has a slight deviation. The actual deviation is 15 ° at maximu
