dc.description.abstract | Molybdenum (Mo), as one of the refractory metals, has been applied in high temperature industrial fields. Powder metallurgy (P/M) is a general process for the production of bulk Mo components because of its high melting point, 2610oC. Generally, sintering of commercial Mo powder with a particle size of several micrometers is performed at elevated temperatures for a long time. It has been reported that a Mo sintered body above 90% of theoretical density could be obtained over a sintering temperature range of 1800-2000oC for several hours. There have been some efforts to reduce the processing cost for a fully densified bulk component with an activated sintering that lowers the sintering temperature to 1200-1400oC through the addition of a small amount of Ni, Pt, Pd, and Co. These sintering aids, however, induce a deterioration of the electrical and thermal conductivity, as well as several mechanical properties | - |
