利用熔点、玻璃化转变温度等易获得的参数并结合准规则模型以及生成热模型,给出了一种计算多元系非晶合金粘度的热力学方法.利用该方法计算了Zr基和Fe基大块非晶合金系的粘度,计算结果与经验结果吻合较好.计算表明,同一温度下,多组元合金系粘度值随组元数增加而增大,粘度随着过冷度的增加而增大；Zr-Al-Ni三元合金在xZr =0.375～0.8571、xNi=0～0.357成分范围内,Zr-Al-Cu三元合金在xzr=0.375～0.8625、xcu =0～0.400成分范围内,Zr66.7Al-Ni-Cu系在xAl=0.632～0.809、xNi=0.145～0.245成分范围内粘度较高；对Fe-基块体合金系,Fe-Nb-B合金系在xNb=0.325～0.9375、xB=0.0625～0.675成分范围内,Fe-Si-B合金在xSi=0～0.521、xB=0.5124～0.9375成分范围内粘度较高.
