Abstract:
In a method for making an article assembly including a brazed joint, the assembly comprising:a first member of a first substrate alloy having a limiting temperature above which at least one adverse member characteristic occurs adversely affecting at least one metallurgical feature of the first substrate alloy which can be brazed with a first brazing alloy at a first brazing temperature less than the limiting temperature; and, a second member of a second substrate alloy requiring brazing at a second brazing temperature greater than the limiting temperature; the steps of: bonding to a surface of the second substrate alloy a second brazing alloy that can be brazed at the second brazing temperature greater than the limiting temperature; and then, brazing the assembly to provide the brazed joint by brazing together the second brazing alloy and the first brazing alloy at the first brazing temperature less than the limiting temperature.
