摘　　要：本文通过对GCr15钢高应变速率超塑试验结果的分析,建立了非典型超塑模型,导出了模型的本构方程。并用方差法分析了影响流变参数的温度和应变速率因素。On the basis of analysing the results of superplastic testing at higher strain rate on steel GCr15,the paper sets up a non-typical superplastic rheology model and derives the constitutive equation,and analyses the factors such as temperature and strain rate that have influence on rheology parameters in the equation by means of mean-square deviation

关 键 词：超塑性 流变 滚动轴承 轴承钢
