【摘要】 用粉末冶金方法 ,使 (Fe- V合金 +石墨 )反应体系在较低温度的固态条件下进行碳化反应和烧结致密化 ,发现石墨的存在降低了 σ- (Fe V)相的稳定性 ,促使其在 80 0℃就分离出少量 α- Fe相和金属 V,并且该体系在 95 0℃即可进行固相反应 ,生成由马氏体基体和大量亚微米级的 V8C7球状颗粒组成的铁基复合材料 ,在重载干滑动磨损条件下该复合材料显示了很好的耐磨性能更多还原

【Abstract】 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 V₈C₇ spherical particles synthesized at 950℃ and the martensitic matrix possesses great wear-resistance under the condition of dry slipping with a heavy load.更多还原
