| Abstract: | 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). |
