Abstract
Successful application of “transformation-toughening” to cemented carbides is demonstrated in the system WC-(Fe, Ni, C). Strict control of the chemical composition of the binder and careful consideration to the effects of thermal residual stress and the constraint imposed by the surrounding carbide grains are essential for achieving the desired degree of metastability of the binder phase that can lead to enhancements in the hardness/fracture toughness behavior of this class of cemented carbides.
