“…The fatigue resistance of several carbon steels (St35, St45, & St50) was reported to be strongly reduced in rotating bending and torsion between 200 • C and 500 • C [329]. Chaevskii and Bichuya subsequently studied the effects of applied strain rate and LBE oxygen concentration on the LME of St50 steels at 400 • C [330,331]. The protective role of oxygen against the steel mechanical degradation due to the action of the HLM was evidenced.…”
