摘　　要：采用水平连续铸造电磁搅拌技术和650℃再结晶热处理进一步改善铝青铜组织及晶粒细化。结果表明:铝青铜轴承材料微观组织为单相α基体中析出K相化合物,且K相均匀、细小,弥散分布在α基体上。组织中α相的平均晶粒尺寸由铸态64.51μm细化到36μm,获得满意的细化效果。The horizontal continuous casting electromagnetic stirring technology and 650℃recrystallization heat treatment have been used to further improve the structure and grain refinement of aluminum bronze.The results show that the microstructure of the aluminum bronze bearing material is a single-phaseαmatrix with K-phase compounds precipitated,while the K phase is uniform and fine which disperses on theαmatrix.The average grain size ofαphase in the structure has been refined from 64.51μm as cast to 36μm and a satisfactory refinement effect has been obtained.
