Author:Osborne, C; Cornish, L; Luyckx, SDate:1997The aim of this work was to produce V8C7-WC and V4C3-WC powders with grain size between 1 and 2mu-m, as a first stage of the preparation of fine grained WC-VC-Co hardmetal. V8C7-WC powder was produced via two routes: starting from preformed ...Read more
Author:Makhele-Lekala, L; Luyckx, S; Nabarro, FRNDate:2001The Vickers hardness of several well-characterized grades of WC-Co (23 in total) was measured. The mean grain size of these samples ranged from 0.6 to 5.0 mums and the cobalt content from 6 to 50 wt%. An empirical formula between hardness of ...Read more
