INFLUENCE OF HYDROGEN BUBBLES FORMING AT SOLIDIFICATION OF SILUMINS ON CASTINGS MICROSTRUCTURE
Thermodynamic analysis of the processes of hydrogen bubbles formation on the crystallizing phases and Al2O3 formation at hardening of silumins is given. It is shown that the most efficient centers of creation and growth of hydrogen bubbles are more plain surfaces of crystals of α- and β-phase.
