Abstract: A method of processing a joint (100), including forming an actively brazed joint (100) in a vacuum furnace, wherein the actively brazed joint (100) is formed from at least two components (102, 104) coupled together by a volume of a joining metal alloy (106, 107) having a solidus temperature and a liquidus temperature, wherein the joining metal alloy (106, 107) Is heated to a first temperature that is higher than the liquidus temperature in the vacuum furnace. The method also includes cooling the actively brazed joint (100) to a second temperature lower than the solidus temperature, and maintaining the second temperature within the vacuum furnace for a predefined duration to form at least one region of segregated crystallization within the volume of the joining metal alloy (106, 107), the at least one region of segregated crystallization is configured to increase the liquidus temperature of a layer of brazed metal, formed from the joining metal alloy (106, 107), between the at least two components (102, 104).
