The effect of shallow cryogenic treatment (SCT) on the microstructure and mechanical properties of Al7075-T6 is investigated in the present work. The alloy was subjected to shallow CT at -80 掳C for 72 h. Mechanical tests such as Vickers hardness test, tensile, and fatigue tests were ...
The tensile results showed the following properties under the T5 heat treatment condition: tensile strength of 359.0MPa; yield strength of 326.1MPa, and; ductility of 28.0%. On the other hand, under the T6 condition, tensile strength was 411.6MPa, yield strength was 373.6MPa, and ductility was...

Light-weight, high-strength, aluminum (Al) alloys have widespread industrial applications. However, most commercially available high-strength Al alloys, like AA 7075, are not suitable for additive manufacturing due to their high susceptibility to solidif
While there were no reports on how the yield stress was defined, the yield stress and the maximum stress should be rather close due to the limited work hardening seen in Fig. 2 and reported for polycrystalline MoSi2 compression tested at the same temperature and strain rate [19]. The ...
The CS 7075 Al was recrystallized after annealing. After PPB hardening, the limiting effect of GB precipitates was limited to grain. It improved intra- and transgranular precipitation. Using low and high-temperature HTs may enhance 7075 Al mechanical properties (stress relief, T7X, T6, and T73...
