Abstract

- The effect of carbide additions is investigated at the atom scale by studying the interface between the cubic carbide phase and the WC prismatic facet in a VC Cr 3 C 2 co-doped WC Co alloy using high-resolution transmission electron microscopy. The alloy was prepared from WC powder about 0.5 lm in size and sintered at 1400°C for 2 h. The orientation relationship between WC and the MC carbide at the prismatic facet of WC is the same orientation as the one found at a WC/(Cr, W)C interface in Cr 3 C 2 -doped alloys. the image of WC shows triangular patterns indicating the position of the C atomic columns in this crystal. In MC crystal, some elongation of the bright areas parallel to the interface is observed on the simulation. The presence of dislocations at interfaces can be related to the parametric mismatch between the two neighboring crystals, to the presence of different stable structural units, or to an angular deviation between the crystals.
