Investigation into fatigue crack propagation in WT-9 titanium alloy

The investigation into basic characteristics of fatigue crack propagation in titanium alloy WT-9 has been presented. The tests have been done on compact tension specimens manufactured from the element of compressor of aircraft engine. The measurement results of the fatigue crack growth rate have been described. The numerical analysis of the results has been provided in order to estimate parameters of the fatigue crack growth rate description.
