Abstract
The outer surface of a stainless steel utensil and one surface of an aluminum disk are cleaned and then separately heated at different temperatures. Thereafter, the disk is superimposed over the utensil and metallurgically bonded directly thereto by the application of pressure. Accumulated stress is relieved by cooling the bonded metal members to a temperature below 250.degree. F., followed by reheating to 700.degree.-950.degree. F.
