Abstract:

Annealing experiments on both irradiated and unirradiated samples of a 2024-T3 Al alloy were followed by metallographic examination, hardness measurements and anal sis of X-ray back reflection patterns. The severely overaged condition of this alloy after neutron irradiation previously reported by Wallack AD-215 540 is shown to be primarily radiation induced and not due only to a high ambient temperature. This overaging is attri uted to an excess vacancy concentration during irradiation equivalent to at least an additional 150 C in sample temperature. Author
