Abstract
A process including brazing a first plate-like member formed from a heat-resistant alloy, and a second plate-like member formed from a heat-resistant alloy and having fins on the surface, with the fins facing the first plate-like member, by interposing a brazing filler metal comprising a melting point lowering element between the two plate-like members, molding the plate-like assembly to form a combustor structural member, identifying, in accordance with the shape of the combustor structural member, strain locations where the strain generated during the press molding step exceeds a predetermined value, performing localized heating of the locations within the plate-like assembly corresponding with the strain locations identified, and as the above press molding step subjecting the plate-like assembly to cold press molding with the temperature of the heated locations corresponding with the strain locations maintained at a desired temperature.
