A Study on the Mechanical Properties and the Fatigue Crack Propagation Behavior of Ti Welding Material

Ti 용접재의 기계적 특성 및 피로크팩 진전거동에 관한 연구

The purpose of this paper was to investigate the welding characteristics and the fatigue crack propagation behavior of titanium commonly using power station, aircraft and ship. The experimented material was TIG welded in order to look over the characteristics according to the notch position and compare with other materials. We compared and reviewed the fatigue crack propagation behavior of nontch base metal and welded specimens having different notch position to evaluate the fatigue crack propagation behavior by welding condition.
