Low concentration of nickel (1wt.%) was used to activate the sintering process in both methods. Isothermal sintering was carried out in alumina tube furnace at temperatures of 1150°C for 2 hr. under H2/Ar. as protective gas. The infiltration (Cu-MI) method proved to be effective in the densification, microstructure and hardness enhancement of the 80W-Cu compact as opposed to the other conventionally liquid phase sintered compacts. The relative densities of 80W- Cu-1Ni composites prepared by using insert method (Cu-melt infiltration) achieved 96.22% of theoretical density. 2014-03-26T02:03:52Z 2014-03-26T02:03:52Z 2013 Article Applied Mechanics and Materials, vol. 372, 2013, pages 34-40 978-303785797-7 1660-9336 http://www.scientific.net/AMM.372.34 http://dspace.unimap.edu.my:80/dspace/handle/123456789/33124 en Trans Tech Publications |
