Abstract

  To elucidate the composition and crystal structure of spheroidal vanadium carbides precipitated in high V-Cr-Ni cast iron that have exhibited excellent performance of anti-corrosive and anti-abrasive properties, alloys of Fe-V-C, Fe-Cr-V-C, Fe-Ni-V-C and Fe-Cr-Ni-V-C systems were prepared and the compositions and structures of vanadium carbides and/or other precipitates were investigated by using SEM, EPMA and XRD. The spheroidal compound was revealed to be a vanadium carbide with an atomic ratio M/C of more or less one and a crystal structure of V<sub>8</sub>C<sub>7</sub> type. The composition and crystal structure of the vanadium carbide remain unchanged even if the alloy concentration or the morphology was varied.
