Abstract

Abstract

A reinforced iron matrix composite with in situ V(C,N) particulates was synthesized by powder metallurgical technique.The microstructure and phase of the composite were tested with SEM and XRD.It was found that the stability of σ-(FeV) was reduced due to the presence of the activated atoms of carbon and nitrogen,and the σ-Fe consisting of V(C,N) particles well-distributed in the matrix were synthesized at 1200℃under the nitrogen condition.The growing up of in situ V(C,N) particulates were inhibited presumably due to the effect of nitrogen in reducing solubility of the particles in the matrix.The volume fraction of V(C,N) particles was up to 50% with particle sizes in the range 0.5~3μm.The composite possesses great wear-resistance under the condition of dry slipping with a heavy load.
