摘要：
A nonflammable Mg-10Al-5Ca (at.%) alloy that can be melted in air without a cover gas or flux is developed. The alloy immediately forms a protective oxide film consisting of three layers, a fine CaO outer layer, a fine MgO intermediate layer, and a coarse MgO innermost layer. The anionic volume ratio of the CaO/MgO interface is 1.48. This interface ratio is sufficiently large to suggest the generation of a strong compressive force in the CaO layer. The dense, uniform fine CaO layer may act as a protective layer preventing the diffusion of oxygen. (C) 2017 Elsevier Ltd. All rights reserved.
