Aluminum alloy 7075 (Al 7075) has been widely used in aerospace and automotive industries to replace heavier alloys. This is because of its superior properties high specific strength, corrosion resistance, good formability, recyclability low fabrication cost. However, the ductility heat generation during drilling Al often produces a burr at entrance exit workpiece surface. research investigates...
In this study, 7075 aluminum alloy with a thickness of 10 mm was successfully welded with no obvious defects by pulsed variable polarity plasma arc (PVPPA) welding. The mechanical properties of PVPPA welded joints have been researched by post weld heat treatment (PWHT). The results indicate that the heat treatment strongly affects the mechanical properties of the welded joints. The tensile stre...
This paper presents a stochastic model of fatigue crack propagation in ductile alloys that are commonly encountered in mechanical structures and machine components of complex systems (e.g. aircraft, spacecraft, ships and submarines, and power plants). The stochastic model is built upon a deterministic state-space model of fatigue crack propagation under variable-amplitude loading. The (non-stat...
This study investigates the mechanical properties and wear behavior of Al 7075/Al2O3/SiCNP composites. The hybrid composites are manufactured using stir casting technique. In this work, 7075 alloy is reinforced with five different weight fractions Al2O3 a constant SiCNp, an average particle size 50 nm. aluminum metal matrix examined through surface morphology X-ray diffraction (XRD) patterns to...
In the present paper, a numerical study is performed to investigate the response of different plates aluminum alloys subjected to low velocity impact condition. In this regard, the square AA5083-H116 aluminum plates with dimensions 300×300 and 3 mm and 5 mm thick under low velocity impact are modelled, and a mesh convergence study is carried out to decide the appropriate number of elements. In ...
Age-hardenable aluminum alloys used in aerospace structures are susceptible to environment assisted fatigue crack propagation (EFCP). There has been no controlled examination of thin film electrolyte, typically produced by atmospheric exposures, effects on EFCP or inhibition of such cracking. The goal of this research is to understand EFCP and inhibition for atmospheric conditions of important ...
