In nuclear research reactors, aluminium alloys are corroded and an hydroxide film covers their surface. Defects created by neutron irradiation can have a detrimental effect on this corrosion. study, two ion irradiations performed 6061-T6 alloy. The first experiment aims at studying the of metal matrix second displacement per atom is most 2.5 dpa in irradiated with Al ions 1.2 5 MeV 8 1.8 (calcu...

The research mainly focuses on the fatigue strength characteristics of 6061-T6 aluminum alloy fillet welds under different vibration frequencies. Firstly, by introducing Stress Life Curve (S-N Curve) and Probability (P-S-N Curve), external stress effects main load-bearing points in environment welded joints are analyzed. Subsequently, a test control system is designed to analyze relationship be...

The material flow and microstructural evolution in the friction stir welds of a 6061-Al alloy to itself and of a 6061-Al alloy to 2024-Al alloy plates of 12.7 mm in thickness were studied under different welding conditions. The results showed that plastic deformation, flow, and mechanical mixing of the material exhibit distinct asymmetry characteristics at both sides of the same and dissimilar ...
