Abstract
In order to improve both of the fatigue and wear resistance of titanium alloy (Ti-6Al-4V), a low temperature nitriding process was developed. This work will evaluate the effects of low temperature nitriding on the microstructure and fatigue properties of titanium alloy. Low temperature nitrided (600°C) specimen showed higher fatigue strength compared to the conventional nitrided (850°C) one. This was because low temperature nitriding can suppress the grain-coarsening of Ti-6Al-4V alloy during nitriding. Then, 4-points bending fatigue fracture mechanism of Ti-6Al-4V was discussed based on the microstructures obtained and from viewpoints of fractography.
