Article Preview

Utilization of finite element method (FEM) and warm compaction process, study on mechanical theory and FEM simulation of molybdenum powder processing. The typical warm compaction process of molybdenum powder was simulated and analyzed with MSC.Marc FEM software. Via calculating, stress field, relative density distribution of molybdenum powder and temperature field were obtained. The result show that when velocity is 5mm/s and pressure is 1000MPa densification is the best. In the molybdenum powder compaction process volume percent of densification zone is 75%.
