Numerical simulation of temperature field during selective laser sintering of polymer-coated molybdenum powder BAI Pei-kang(白培康), CHENG Jun(程 军), LIU Bin(刘 斌), WANG Wen-feng(王文峰... laser sintering was introduced. Based on the research of laser heating property, powder thermal physics parameters and laser sintering process, a numerical model of the temperature field during length......
. Double shielding gas argon was used at both sides of workpiece to avoid the oxidation of liquid metal. The laser beam irradiated the workpiece vertically, and there was focal spot position at the top... leads to the reduction of Si chemical potential. Therefore, Si atom in liquid filler diffuses to the interface during laser joining, and then Si gathering phenomena appear at the interface. Table 1......
al [23] built a 3D laser welding (LW) model to simulate the heat transfer and flow of liquid metal. Level set approach was used in their model to track the free surface boundary. However, the plasma... software Fluent. The 3D keyhole evolution process was presented. PANG et al [30, 31] developed a multiphase model to study the flow of liquid metal and metal vapor in keyhole in laser welding......
