| Abstract: | More attention has been paid to the research on titanium alloy in the manufacturing and repairing of aircraft structures for its good mechanical properties. We present our experimental study of fatigue behavior of titanium alloy welded with argon arc with hand-made tungsten poles after rolling treatment under tension fatigue load. With a large quantity of experimental data, we perform the statistical analysis of incomplete fatigue life in accordance with reliability theory. |
