Abstract
During additive manufacturing process of alloys, element segregation is vital in determines the solidification structure and mechanical properties of components. In this work, the solute trapping behavior and Nb segregation during laser additive manufacturing of a nickel-based superalloy are studied via a multi-scale model. The temperature evolution of the molten pool is estimated by the macro-scale mass and heat transfer simulation, and the...
