摘要: An improved mass addition approach based on enthalpy balance is used for the numerical simulation of temperature distributions and geometries during laser rapid manufacturing (LRM) a multi-layered thin-wall. The involves estimation local track height at every node along width substrate/previously deposited layer by simultaneous balancing excessive enthalpies above solidus about axis material interface multi-layer thin wall. It takes power, beam size, scan-speed, powder feed rate, stream diameter, time-delay between deposition two subsequent tracks as user-defined input, computes layers across process domain in dynamic fashion. In present study, five layered walls SS 304L ...
