摘要：

The　densification,　microstructure　and　hardness　of　molybdenum　prepared　by　spark　plasma　sintering　(SPS)　were　investigated.　SPS　is　an　advanced　rapid　sintering　technique　with　a　lower　temperature　and　shorter　time,　compared　with　other　sintering　techniques.　The　molybdenum　sintered　by　SPS　at　180-500　°C　lower　than　by　CIP-S　and　HP　and　in　holding　time　of　3　min　obtained　relative　density　of　95.2%-97.9%　and　hardness　HV20-HV75　higher　than　that　by　other　sintering　techniques.　The　density　of　molybdenum　sintered　by　SPS　increases　and　the　hardness　of　molybdenum　decreases　with　the　temperature　increasing.　The　molybdenum　sintered　at　lower　temperature　by　SPS　having　higher　hardness　is　due　to　fine　grain　strengthening.　The　fracture　mode　of　SPS　sintered　molybdenum　belongs　to　brittle　intercrystalline　fracture.
