| Abstract |
SEM observations and Vickers-hardness tests were performed to identify the irradiation effects. γ-
irradiation effect during the aging hardening process can be explained depending on the
composition of the alloy and is used to derive quantitative information on the kinetics of the
transformation precipitates. Increasing the Cu content of an Al-Cu alloy can improve the aging
hardness. The present results of hardness behavior with SEM observations of surveillance
specimens at different doses suggest that the radiation-induced defects are probably complex
valance-solute clusters. These clusters act as nuclei for the precipitation of θ-Al2Cu type. This can
be effectively utilized to study the systematic of nucleation of precipitates at vacancy-type defects.
γ-irradiation probably play the key role in defects responsible for material strengthening and
embrittlement. |
