PROBLEM TO BE SOLVED: To provide a hybrid diffusion-brazing process and a hybrid diffusion-brazed article.SOLUTION: The hybrid diffusion-brazing process includes preparing a component 101 having a temperature-tolerant region and a temperature-sensitive region, brazing a braze material 103 to the temperature-tolerant region 105 during a localized brazing cycle 100, then heating the component in a furnace 202 during a diffusion cycle. The brazing and the heating diffusion-braze the braze material to the component, and the localized brazing cycle is performed independent of the diffusion cycle in the hybrid diffusion-brazing process. The hybrid diffusion-brazed article includes a component, and a braze material diffusion-brazed to the component with a filler material. The filler material has a melting temperature that is above a tolerance temperature of the component. 【課題】ハイブリッド拡散蝋付け方法およびハイブリッド拡散蝋付け製品を提供する。【解決手段】ハイブリッド拡散蝋付け方法は、耐熱領域および温度感受性領域を有する構成部品１０１を準備し、局所的蝋付けサイクル１００の間に蝋付け材料１０３を耐熱領域１０５に蝋付けし、次いで、拡散サイクルの間に構成部品を炉２０２中で加熱することを含む。蝋付けおよび加熱は蝋付け材料を構成部品に拡散蝋付けし、局所的蝋付けサイクルはハイブリッド拡散蝋付け方法における拡散サイクルから独立して行われる。ハイブリッド拡散蝋付け製品は構成部品、および溶加材で構成部品に拡散蝋付けされた蝋付け材料を含む。溶加材は、構成部品の許容温度よりも高い融解温度を有する。【選択図】図１
