To analyze the influence of processing conditions on the melt pool geometry and dilution ratio of the Ni-based alloy during laser cladding, a finite element model of heat transfer and fluid flow with multi-physical parameters was established. This model is used to simulate the temperature and velocity fields of melt pool. Thermodynamic processes such as phase transition, Marangoni convection and buoyancy...
Insight into the physical mechanism in the process of selective laser melting is essential to improve the quality of parts, and meanwhile, the existing research on process parameters for new materials is lengthy and complex, it often takes a lot of time and effort. In this paper, the influence mechanism of surface tension on the morphology of melt track under different boundary conditions is analyzed,...
