摘要: The influence of T6, RRA, second aging(T6I6) and high-temperature pre-precipitation(HTPP)aging on the mechanical properties and corrosion behavior of 7075 aluminum alloy and its mechanism were investigated by tensile test, intergranular corrosion test and TEM observation.关键词:...
In this study, microstructure and mechanical properties of a 7075 aluminum alloy subjected to multipass FSP, MP-FSP, were assessed to obtain fundamental knowledge for improving the plasticity of aluminum alloys. The MP-FSP was applied to 7075 alloy plates with T6 and O tempers, and ...
The microstructure and lap shear properties of refill friction stir spot welded dissimilar 7075/6061 aluminum alloys joints were studied. 7075 aluminum alloy was used as the upper sheet. The effect of sleeve plunge depth on joint formation and mechanical properties were discussed. The results showed...
There is uncertainty in theinitial size of the crack(what size crack can be detected), the stress levels experienced during operation, and thecrack growth rate properties of the material. The factor of safety can be calculated with respect to stress (considering maximum applied stress as compared...
Key words: Al-Zn-Cu-Mg-Sc-Zr alloy; retrogression and re-aging treatment; microstructure; mechanical properties; stress corrosion cracking compared with that of the T6 temper [8]. Therefore, it is 1 Introduction necessary to explore a new aging treatment to decrease the susceptibility of SCC ...
Aluminum alloy 7075 is a useful material in industry due to its light weight, high strength, and resistance to general corrosion properties. The drawback of this alloy is its susceptibility to stress corrosion cracking (SCC). From the previous research, it was found that retrogression and re-ag...
In the present study, refill FSSW was performed in a 0·8 mm thick AA7075-T6 aluminium alloy with varying welding parameters (welding time and plunge depth). The influence of welding parameters on the microstructure and mechanical properties of the weld was investigated in terms of nugget ...
So the laser beam welding can be considered as a promising technique to weld aluminum alloys. However, the microstructure characteristics and mechanical properties of the LBW joints in Al–Zn–Mg–Cu alloys are not entirely clear because they are treated as unweldable materials so far. So it ...
