Binder-Carbide Phase Interactions in Titanium Carbide Base Systems
Binder-carbide phase interactions have been investigated in titanium carbide base systems using the Energy Dispersive X-ray Analysis (EDXS) capability of the scanning transmission electron microscope (STEM). Concentration gradients of Mo and V within carbide grains are shown after sintering in the presence of a Ni-rich liquid phase. Binder Ti and Mo levels were measured using this technique, which has a major advantage over phase separation analysis due to the ability to locate the analysis position with respect to the microstructural components.
