SUMMARY
The discussion centers on the proof stress of aluminium alloys, specifically addressing the differences observed when tested in bending versus tensile conditions. It is established that microstructural variations, such as grain size and phase distribution, significantly influence the mechanical properties of aluminium alloys. The bending test often results in higher proof stress due to the strain hardening effect and the distribution of stress across the material. This phenomenon is particularly relevant for alloys like 6061 and 7075, which exhibit distinct microstructural characteristics under different loading conditions.
