Hybrid diffusion-brazing process and hybrid diffusion-brazed article

A hybrid diffusion-brazing process, comprising:

• providing a component comprising a first region having a first tolerance temperature and a second region having a composition different than the first region, wherein the second region has a second tolerance temperature and the first tolerance temperature is greater than the second tolerance temperature;
• brazing a braze material to the first region by localized heating to a braze temperature to melt a filler material comprising melting point depressants by a localized heating source during a localized brazing cycle;
• then
• heating the component in a furnace to a diffusion temperature during a diffusion cycle to facilitate diffusion of the melting point depressants into the braze material and the first region of the component, wherein the diffusion temperature is in the range of 1800° F. to 2050° F.;
• wherein the second region remains below the second tolerance temperature during the localized brazing cycle;
• wherein the second tolerance temperature is in the range of 2100° F. to 2300° F.;
• wherein the braze temperature is greater than the second tolerance temperature for the second region and the second tolerance temperature for the second region is greater than the diffusion temperature;
• and
• wherein the localized brazing cycle is performed independent of the diffusion cycle in the hybrid diffusion-brazing process.
