| Abstract | The flow of the feedstock during its inject into a complex-shaped mould is studied. The model of nonlinear viscosity flow is used for the feedstock behavior analysis. The dependence of the shear viscosity effective coefficient on the powder concentration in the feedstock was determined by methods of computing micromechanics. The rheological equation of the feedstock contains the stuff (particles) concentration as a parameter. Using computer simulation, the optimization of the orifice for argon-arc welding as an example of a complex-shaped mold filling with feedstock (selection of the injection gate location) has been carried out. The results showed that the most uniform mold filling and the minimum number of defects were reached in case of the injection gate location at the narrow end of the orifice. |
