Abstract
The effect of phase composition, fineness, and morphology of W-Re powders w ith different rhenium content on compaction and formation of porous structu re has been studied Fine particle powders with a specific surface of 5-8 m( 2)/g, mechanical mixtures of tungsten and rhenium powders, and W-Re alloy p owders were used. Local nonuniform compaction is observed during sintering of powder mixtures and alloy powders. It was established that alloy powders and intermetallic powders have lover sintering activity.
