Abstract：

The warm compaction process of molybdenum powder was simulated and analysed with MSC.MAARC FEM software by using themal-mechancial coupled method.The correlative data,including geometrical deformation,stress field and relative density distribution of molybdenmu powder were obtained for optimizing warm compaction technology patamters.
