The consolidation of pure tungsten carbide (WC) powders, without a binder phase to activate the liquid phase sintering, requires advanced and costly current and pressure assisted sintering techniques. Binder-free WC products are typically produced by spark plasma sintering (SPS), achieving very high densities (98-99+%) and hardness (28-30 GPa). Although, the material toughness is generally limited to 4-6 MPam1/2, a value too low for any structural application of monolithic WC. Thus, the use of such ceramic as structural components requires new strategies to make this material more damage tolerant, which translate in altering the intrinsic toughening mechanisms of WC. A change in the deformability of hard ceramics has been recently reported for 3YSZ and TiO2 processed by the flash sintering technique. Abundant post-flash defects, like dislocations, lead to improved plasticity in certain circumstances. This work investigates the effect of the flash event on the deformability of WC. Micropillars were produced by focused ion beam (FIB) on material consolidated by FS and SPS, and compressed at room at high temperature (700ºC) inside a FESEM (in-situ) to disclose any activation of plasticity between the two materials.
