Post irradiation changes of the elastic modulus of aluminum

Author

Abstract

"Aluminum samples of 99.99% and 99.999% purity were irradiated to neutron fluences of 3·8·10¹⁸ nvt and 1.4·10¹⁹ nvt (E greater than 0.1 Mev) at one-third of the melting temperature. The change in Young's modulus of elasticity after isothermal annealing in the temperature range of 110⁰C to 130⁰C was measured. After 2.5 hours of annealing, the modulus reached a steady state value which was decreased by 0.25% ± 0.17% from the unannealed value. Electron microscopy suggests the hardening mechanisms were dispersion hardening by silicon precipitates and void hardening"--Abstract, page ii.
