Finite element (FE) simulation with inherent deformation is an ideal and practical computational approach for predicting welding stress and distortion in the production of complex aluminum alloy structures. In this study, based on the thermal elasto-plastic analysis, FE models of multi-pass butt welds and T-type fillet welds were investigated to obtain the inherent strain distribution in a 5A06...

In this article, failure and fracture mechanisms in an aluminum alloy (which has been used in diesel internal combustion engines), with and without ceramic thermal barrier coatings, have been investigated under isothermal and non-isothermal fatigue loadings. In this research, the base material is an aluminum-silicon-magnesium alloy and the thermal barrier coating includes a metallic bond coat l...

The rolling correction process can eliminate machining distortions of aluminum alloy 7075-T651 structural parts. thermal stability the corrected parts under action temperature loading, especially macroscopic shape stability, is key to ensure safe service mechanical equipment. In this study, different loads were used postprocess after correction. rolled samples was analyzed by characterizing mic...

in this research using statistical analysis the effect of machining parameters such as cutting velocity, feed rate, and tool type on machining power (p m ) in machining process of en-ac 48000 aluminum alloy has been studied. a taguchi l 27 standard array has been utilized as the most economical array to evaluate the factors and their interaction. en-ac 48000 alloy is frequently used in automoti...

The stress corrosion cracking (SCC) of different aging states for 7050 aluminum alloy in 3.5% sodium chloride aqueous solution has been studied by means of double cantilever beam (DCB) specimens, cathodic polarization, scanning electron microscope (SEM), transmission electron microscope (TEM) and time-of-flying second ion mass spectrometer (ToF-SIMS). The results showed that the susceptibility ...
