In this work, the effect of increase argon pressure applied on a post-sintering treatment from MPa to MPa on the mechanical properties of a newly developed hardmetal grade, namely hardness, flexural strength and fracture toughness, is reported. The as-received material has been prviously sintered at 1460ºC under 2 MPa argon pressure from powder mixtures of WC and 3,5 wt% Co together with minor additions of VC, ...
