Abstract Using powder metallurgy technology, the system of (FeV+graphite) finished carbonized reacts and VC iron matrix composite fabricated in situ in vacuum furnace. SEM，XRD and TEM were used to examine the structure and phase of composite. The wear-resistance of VC iron matrix composite was examined on a MM-200 wear-test machine. It was confirmed that graphite reduced the stability of σ-（FeV）, and σ-（FeV）decomposed small quantity of α-Fe and V at 1073K.The composite was mainly made of VC particles and α-Fe, and displayed good wear-resistance under dry sliding with heavy load.
