Outline of Final Research Achievements

The purpose of this study is to develop a technology to prevent the internal oxidation of rare-earth elements to Mg alloys. This technology achieves not only ensures the safety but also the integrity of the molten metal.
We add the fourth element to rare-earth element-containing Mg alloy in order to suppress the internal oxidation of rare earth elements and form a homogeneous and dense protective oxide film. Furthermore, high-strength nonflammable wrought Mg alloy was developed in this study.

Academic Significance and Societal Importance of the Research Achievements

本研究は、希土類元素添加マグネシウム合金で発生する内部酸化現象に着目し、マグネシウム合金に高次の不燃性を付与する合金設計指針を確立することができたことが学術的および社会的意義となる。内部酸化発生メカニズムの解明は、今後、新規の希土類元素添加マグネシウム合金を開発するにあたって、重要な基礎データとなる。また、高温でマグネシウム合金で発生する内部酸化を抑制することで、高温での酸化皮膜の健全性を向上させることができたことで、マグネシウム合金の発火温度の増加という安全性だけでなく、鋳造などのマグネシウム合金の製造工程での溶湯の汚染を抑制することができた。
