ABSTRACT
Aluminum and its alloys react with the ambient atmosphere during melting and casting. It is found that aluminum and aluminum alloy components can interact with hydrogen, nitrogen, water vapor, carbon monoxide (CO), and carbon dioxide (CO2) [27-29]. In small quantities, there are hydrogen and oxides in alloy, which have a significant influence on metal properties. At the beginning of this study in 1960, there were no systematic data on the behavior of lithium-containing aluminum alloys in liquid state, except for some information about the general laws of lithium influence on the oxidation of different metals stated in Shamrai [30], and there have been summary reports of difficulties in melting and casting of aluminum-lithium alloys because of their high aggressivity in liquid state.
