The concentration of Co addition used ranged from 0.5 to 3wt. %. The infiltration temperatures were performed at 1150°C and 1250°C for 2 hr under vacuum. The microstructure and sintering density of W-25Cu composites are discussed. Results indicated that, the relative density (RD) and microstructure of W-25wt. % Cu were greatly affected by the addition of low Co concentration and sintering temperature. The concentration of 3 wt. % Co to tungsten-copper compact and infiltration temperature of 1250°C give high sintering density of 98.6% theoretical density (TD). The concentration of Co and infiltrating temperature have strong effects on the densification of W-Cu composite materials. The sintered compact microstructures and density were obtained using scanning electron microscope (SEM) coupled with EDX and Archimedes technique respectively. 2014-03-09T10:29:13Z 2014-03-09T10:29:13Z 2012-12 Article Advanced Materials Research, vol.626, 2012, pages 430-435 1662-8985 http://dspace.unimap.edu.my:80/dspace/handle/123456789/32465 http://www.scientific.net/AMR.626.430 en Trans Tech Publications |
