Аннотация
The kinematic viscosity of a liquid Al–7% Si + 5% Al2O3 aluminum matrix composite material formed by oxygen blowing of a preliminarily hydrogenated melt is studied using torsional vibrations and is compared with that of the initial alloy. The photometric method has revealed the fraction of oxide particles in the aluminum matrix. No branching of the polytherms of the composite material melt is observed, which is related to the microheterogeneity inherent in the melt. The viscosity of the composite material is shown to be predicted from the well-known dependences with allowance for the fragmented shape of the dispersed phase particles. These results can be used to calculate pouring gate systems.
