Abstract
⺠Effect of W and C variation in A.R. white cast iron was studied up to 12 wt% W. It never exceeded 10 wt% in previous investigations. ⺠Carbide morphologies with 2.2-3.2 wt% carbon shows that W has dominating effect on carbide morphology. ⺠New carbide microstructures (GA and IA) appear in some range of carbon and its volume fraction is function of carbon content. ⺠After heat treatment, new carbide morphology turns to continuous chromium carbide. ⺠Wear resistance and hardness of the new alloys depends on both IA appearance presence and tungsten carbide precipitation.
