Self-similar approximation for the process of formation of microporosity in alloys of light metals

A physical and mathematical model is proposed for description of the formation of microporosity in an alloy within the framework of the two-phase zone approximation with account for the real state diagram of the alloy. The formation of microporosity in an Al–Si melt in the process of its solidificat...

Description
Summary:A physical and mathematical model is proposed for description of the formation of microporosity in an alloy within the framework of the two-phase zone approximation with account for the real state diagram of the alloy. The formation of microporosity in an Al–Si melt in the process of its solidification as a result of the liberation of hydrogen from it was investigated in the self-similar approximation. The influence of the parameters of solidification of this alloy on the formation of a gas microporosity in it was analyzed.
