Iron Matrix Composite Reinforced by VC Particulates Produced by Solid Reaction
Using the powder metallurgical technology,the carbonized reaction and sintering compaction of Fe-V alloy and graphite was carried out on the solid state condition. It is found that the stability of σ-(FeV) is down, the α-Fe and metal V are separated at 800℃,and the ferrous matrix composite consisting of a large number of superfine V_8C_7 spherical particles synthesized at 950℃ and the martensitic matrix possesses great wear-resistance under the condition of dry slipping with a heavy load.
