Fe-(WTi)C composite granules containing up to 80 wt-% carbide have bee
n produced by a selfpropagating high temperature synthesis reaction. T
hese can be readily distributed in conventional steel melts. Additions
up to 17 wt-% carbide have been made to a 0.4 wt-%C steel which was s
ubsequently cast and hot rolled to plate. The microstructures of cast,
rolled and heat treated samples display a homogeneous distribution of
carbides which do not significantly affect the rolling performance of
the steels. The carbides and grain refinement in heat treated samples
result in a marked improvement in mechanical properties. The most sig
nificant improvement as a fraction of carbide additions is seen in abr
asive wear performance.
