摘要

•A three-dimension finite element model during LMD of W-20%Fe was established.•Dimensions of the molten pool at different laser powers were discussed.•Evolution of thermal behavior and melting/solidification process were studied.•Solidification behavior and mechanisms of microstructure were concluded.
