SINTERING OF NANOCRYSTALLINE TUNGSTEN POWDER

摘要

Small metal samples have been made from nanocrystalline tungsten powder by sintering with the goal of producing high density parts. The parameters associated with sintering runs have been examined to see if there is an empirical relationship between them and the final part density. A function that depends on the time the sample spends above a critical temperature has been formulated that represents one specific batch of tungsten powder. The function has been applied to other batches of powder with some success.
