Modeling of Thermal-metallurgical Behavior during Hybrid Plasma-laser Deposition Manufacturing

摘要：

A three-dimensional nonlinear finite element method combining with Monte Carlo model was developed to investigate the temperature field and grain growth in the heat affected zone (HAZ) during the plasma-laser hybrid deposition manufacturing (PLDM) thin wall metal parts. The numerical study shows that the temperature gradient directly decides the grain growth speed in the HAZ of deposited wall. However, the effect of thermal impact due to continuous scanning of laser and plasma arc on the microstructure in the substrate material is negligible. This thermal-microstructure model could be further applied to study the variable high energy forming processes.
