Abstract
A process for heat treating certain nickel-chromium-iron alloys is disclosed which involves annealing the alloys over the temperature range of 1750.degree. F. to 2150.degree. F., preferably in a continuous annealing furnace, for short periods of time, such as 30 minutes to 2 hours, the time being sufficient to precipitate carbides at the alloy grain boundaries. The alloys are useful in nuclear reactor environments.
