摘    要:对相同粉末装载量的4种粘结剂体系的Fe-NiMIM注射料的粘度和流变行为研究了研究,采用毛细管流变仪,获得MIM注射料对不同显度,不同剪切速率下的粘度值,分析了MIM注射料的流动性能,粘度对应变速率的敏感性,粘度对温度的敏感性,比较了各粘结剂的粘度和注射料的流动性指数的差异。

关 键 词:金属注射成型  注射料  粘度  流变行为  粉末冶金

Abstract:The viscosity and rheological behavior of Fe-Ni MIM feedstock with four kinds of binders were studied. The viscosity of MIM feedstock at different temperature and shear rate were measured throush capillary rheometer. The flowability, sensitivity of viscosity to shear rate , sensitivity of viscosity to temperature were investigated. The viscosity of binders and the moldability parameter of feedstock were compared.
Keywords:metal injection molding  feedstock  viscosity  rheological behavior
