Fe-Mo-(Ni/Cu)-石墨粉末冶金复合材料的制备及组织性能研究
Research on microstructure and properties of Fe-Mo-(Ni/Cu)-graphite composite prepared by powder metallurgy technology
摘要
Abstract
Fe-Mo-Ni-graphite (FMNG) and Fe-Mo-Cu-graphite (FMCG) composites were fabricated by powder metallurgy technology.The effects of Ni and Cu elements on microstructure,composition,hardness,and compressive strength of the prepared composite were investigated.Experimental results show that,the composites are mainly composed of pearlite,ferrites,bainite,Mo2C and Fe3Mo3C strengthening phases,and clustered graphite.The hardness and compressive strength are improved by heat treatment.The hardness of FMCG is lower than that of FMNG.The compressive strength of FMCG is higher than that of FMCG It is suggested that,the addition of Ni and Cu and the heat treatment can affect the microstructure and properties of the materials.关键词
