INFLUENCE OF HIGH POWER BALL MILL TECHNOLOGY ON STRUCTURE OF TUNGSTEN-COPPER COMPOSITES

Open publisher page 3 citations

Abstract

W-15% Cu powder mixtures were mechanically alloyed in a planetary high power ball mill.The influence of milling time on the structure of tungsten-copper composites were studied.The milled powders and sintered samples in different milling times were analyzed using XRD and SEM.The results show that the grain size of power is decreased and the relative density of the sintered samples is increased with the milling time.The relative density of W-15% Cu composite sintered at 1350℃ after ball milling for 60h reached 98.8%.
