Abstract
An article assembly comprising a plurality of members includes a multi-layered brazed joint provided in the assembly between a first member that can be affected adversely by thermal exposure at a limiting and a second member requiring exposure, such as for brazing, at least at the limiting temperature. The assembly is provided with a multi-layered brazed joint directly or indirectly between such members by brazing to the second member a second brazing alloy that can be brazed at a temperature required to braze the second member, providing a preform. The assembly is brazed to include the first member by brazing members of the assembly together with a first brazing alloy, brazing at a temperature less than the limiting temperature, brazed at the second brazing alloy.
