Abstract:

Molybdenum nanoposders have been synthesized in a RF plasma by controlling the various process paarameters. The obtained Mo nanopowders are characterized by SEM, TEM, and XRD. Mo nanopowders are sintered to a pellet with ultra-fine grain by two step sintering process. Mechanical properties of ultra-fine grained Mo with relative density of above 90% were significantly improved at room and high temperatures comparing to commercial bulk Mo of 99% relative density.
