After experimental identification of the main factors influencing Inconel 738LC superalloy microstructures, a semi-analytical modeling of precipitate dissolution during thermal cycle has been proposed. It was based on an isokinetic model of phase transformation adapted to the presence of high-precipitate density as observed in γ' precipitate hardened IN738LC. Some data required as input for the semi-analytical modeling could be determined by an inverse method applied to isothermal treatments. Finally the semi-analytical modeling was validated through non-isothermal treatments and used to predict the occurrence of hot cracking depending on welding conditions.Read less <
