摘 要: 使用非牛顿流体幂律模型和 Cross模型 ,对 W- Ni- Fe高比重合金粉末喂料熔体的实验测得流变数据进行回归分析、曲线拟合 ,得出各自的拟合常数 ,并对拟合结果进行了比较 ,为金属粉末注射成形分析模拟软件提供了实用的数据。 Using non-Newtonian fluid power-law model and cross model, the regression analysis and curve fitting were done for the rheological data of W-Ni-Fe heavy alloy powder feedstock melt from experiment. The regression coefficients were obtained and the results was analyzed. Practical data were provided for the numerical simulation software of metal injection molding(MIM).
