Cracking mechanism and susceptibility of laser melting

Dec 05, 2019 · Laser Melting Deposition (LMD) of Inconel 738 (IN738) superalloy is a promising process for the remanufacturing of gas turbines and aerospace engines, but the cracking has not been thoroughly understood and controlled. Creep Life Prediction of Inconel 738 Gas Turbine BladeCreep Life Prediction of Inconel 738 Gas Turbine Blade. The aim of this study is life prediction of IN738 LC gas turbine blade via Larson- Miller parameter method and fulfillment of some systematic metallographic, creep and hardness tests. Various calculative methods of remaining life prediction have been considered and Larson-Miller parameter
