HEAT TREATMENTS FOR IMPROVED DUCTILITY OF Ni-Cr-Co-Mo-Ti-Al ALLOYS

Abstract:

In a method for heat treating alloy compositions within UNS N07028 the alloy composition is heated at a temperature between 1550.degree. F. and 1750.degree. F. for at least two hours, and then heated at a lower temperature between 1300.degree. F. and 1550.degree. F. for at least two hours. The alloy composition may be heated at a temperature between 1850.degree. F. and 1950.degree. F. for at least one hour before heating the alloy composition at a temperature between 1550.degree. F. and 1750.degree. F.
