A Study on the Fatigue Life Characteristics of Heat-Resisting Steel
내열강재의 마찰용접에 따른 피로수명 특성에 관한 연구
Abstract
The fatigue crack propagation characteristics were investigated for two kind of heat-resisting steel(STR3 and STR35) commonly using in valve material of vehicles. From the experiment, the fatigue life of the specimens notched at bonded line was shown about 19.7% and 72.2% lower and the specimens notched at 1.0mmdistance from bonded line was shown about 25.2% and 99.1% higher than that of the base metal respectably.
