WC-10Co-xVC alloys were produced using two different sizes of WC powders (200 nm and 4.4 mm) via planetary milling and a liquidphase sintering technique. When VC was added to the WC-Co alloys, the growth of WC particles was effectively suppressed. However, this process was dependent on the amount of additive used. Since the average WC particle size became less than 1 mm, the system experienced a

Growth Inhibition of Nano WC particles in WC-Co Alloys during Liquid-Phase Sintering

The progress made with respect to equipment used in the hardmetal industry over approximately the last 50 years is reviewed. The manufacturing areas considered range from chemical processing of the tungsten bearing ores to the final sintering of the hardmetal compact. PM/0223
