Abstract: A brazing process, a braze arrangement, and a brazed article are disclosed. The brazing process includes brazing an article with a braze arrangement. The braze arrangement includes a first braze material and a second braze material, the first braze material having a first melting point and the second braze material having a second melting point, the first melting point differing from the second melting point. The brazed article includes a treatment region, a first brazed material positioned within the treatment region, and a second brazed material positioned distal from the article in comparison to the first brazed material. The first brazed material is formed by the first braze material and the second brazed material is formed by the second braze material.
