Abstract: A hybrid diffusion-brazing process and hybrid diffusion-brazed article are disclosed. The hybrid diffusion-brazing process includes providing a component having a temperature-tolerant region and a temperature-sensitive region, brazing a braze material to the temperature-tolerant region during a localized brazing cycle, then heating the component in a furnace 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.
