In last few decades, the operating temperatures of gas turbine engines have been continually increased in order to achieve higher and higher power and efficiency. During the operation of power generation gas turbines, the blade and other components of hot gas path undergoes service induced degradation, which may be neutral or accelerated due to different causes. The degradation or damage may have a metallurgical or mechanical origin and results in reduction of equipment reliability and availability. It also increases risk of failure occurring. Also, due to blade material metallurgical deterioration, the material creep, fatigue, impact and corrosion properties decrease. There are different factors which influence blade lifetime as design and operation conditions but the latter are more critical.
