Abstract
PURPOSE: To obtain a sintered Mo body with superior machinability by compacting Mo powder having specified average particle size and sintering the green compact at a specified temp.
CONSTITUTION: Mo powder having 3W3.5μm average particle size is compacted into a prescribed shape after adding an org. binder as required. This green compact is sintered at 1800W1900°C in a reducing atmosphere for a prescribed time. The reason why the particle size of the Mo powder is restricted as mentioned above is that the machinability of the resulting sintered body is deteriorated in case of ≤3μm average particle size, and Mo powder having ≥3.5μm average particle size is difficultly freed of air during compacting, whereby the green compact is apt to crack.
