摘　　要：从理论上对金属注射成形喂料的流变学性能进行分析发现，评价ＭＩＭ喂料流变学性能的主要指标是喂料的粘度及粘度对应变和温度的敏感性，这些指标可统一用ＭＩＭ喂料综合流变学因子进行评价。运用该评价因子研究了几种不同粘结剂组成的Ｆｅ－Ｎｉ及Ｗ－Ｎｉ－Ｆｅ合金喂料的流变学性能。The rheological properties of metal injection molding (MIM) feedstocks were analyzed theoretically It was found that the evaluation system of the rheological properties of MIM feedstocks included the feedstock viscosities and its sensitivity to the shear rate and the temperature, which could be described as a general rheological index for MIM feedstocks The rheological properties of several kinds of FeNi and WNiFe MIM feedstocks with different binder composition were evaluated using the general rheological index for MIM feedstocks
