Abstract : The viscosity of cast irons of the systems Fe-C, Fe-C-Si; and Fe-C-Si-Al was measured at 1280-1460 degrees. The aim of the work was to study the 'heredity' of the castings whose properties depend on the starting material. The results confirm the existence of a viscosity hysteresis in superheating and cooling cycles and considerable viscosity differences in melts of the same chemical composition. These phenomena are due to incomplete dissolution of graphite in the melt and the formation of microclusters. (Author)
