【発明の詳細な説明】
（産業上の利用分野）
本発明は電子ビーム溶解炉におけるＡｌの添加方法に関
する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method for adding Al in an electron beam melting furnace.
（従来の技術）
電子ビーム溶解炉を用いたＭ合金の溶解方法はＭをＴｉ
と一緒に電子ビームにより溶解していた。(Prior art) A method for melting M alloy using an electron beam melting furnace is to replace M with Ti.
It was melted together with the electron beam.
（発明が解決しようとする課題）
電子ビーム溶解方法においては高真空状態であると共に

Electron beam gun (1) in a vacuum state of torr or higher
After T1 is melted by irradiating it with an electron beam, rod-shaped or granular AA is introduced from the material input device (3) as shown in Fig. 2, and M is the melted Ti in the water-cooled copper crucible (4). It is melted by the amount of heat, and the casting is performed after the mold (5) is raised by a mold raising device (6).
