  • Description: Indentation-induced surface and subsurface deformation mechanisms in directionally solidified WC-W.sub.2C eutectoids are investigated. The microstructures of the WC-W.sub.2C composites consist of primary WC regions, W.sub.2C-rich regions, and lamellar-type eutectoid regions, which form during the sequential phase transformations during laser processing. Indentation-induced surface crack profiles indicate little propensity for debonding at the WC-W.sub.2C eutectoid interfaces, although some interactions with larger-scale microstructural features are observed. In the subsurface indentation regions, dislocation networks predominantly composed of partial dislocation pairs having Burgers vectors [Formula omitted] are observed in the primary WC regions, whereas shear banding and grain refinement are commonly observed in the micrometer-scale W.sub.2C-rich regions. Deformation in the sub-micrometer eutectoid regions is distinct, with the dislocation activity primarily limited to the WC phase, with Burgers vectors of [Formula omitted] that terminate at the interfaces.
