Abstract: A process for joining together two components is disclosed. One component is an outer component made from a first material having a first coefficient of thermal expansion. The second component is an inner component made from a second material having a second coefficient of thermal expansion. The process relies on differences in thermal expansion of the materials to bring mating surfaces of the components into close contact with a metallurgical bonding material so that the bonding material is shielded from contact with the atmosphere. Consequently, the bonding process is not affected adversely by reactions between the bonding material and oxygen.
