HEAT TREATMENTS FOR IMPROVED DUCTILITY OF NI-CR-CO-MO-TI-AL ALLOYS

摘要

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