In the present study, an attempt has been made to investigate the influence of the forging parameters on cutting forces for different cutting speed, depth of cut, and feed rate during machining of Al 7075 alloy and Al 7075 alloy with short basalt fiber reinforced metal matrix composites. The experiments were conducted by using a lathe machine with tool dynamometer setup. KeywordForging effect, ...

For the aeronautics industry, constraints of mechanical strength are paramount. Aluminum and its alloys widely used for various household industrial applications. Among established identified aluminum alloys, 7075 alloy, which is an aluminum-zinc, acquires best strength. However, this sensitive to certain localized corrosion phenomena such as pitting corrosion. Pumpkin seeds (PS) were evaluated...

In this paper the capability of Gurson-Tvergaard-Needleman (GTN) model in the prediction of ductile damage in 7075-T651 aluminum alloy is investigated. For this purpose, three types of specimens were tested: Standard tensile bars, Round notched bar (RNB) specimens and compact tension (C(T)) specimens. Standard tensile bar tests were used to obtain the mechanical properties of the material and t...

entropy as a measure of uncertainty was used to represent the results of the wavelet technique in electrochemical noise analysis. the experimental signals were obtained by recording the electrochemical potential and current noise of 7075 aluminum alloy in 3.5% nacl solution. the electrochemical potential and current noise were decomposed into 16 levels using daubechies wavelets. wavelet output ...

In this paper, we studied the oxidation behavior in AA7075 containing TiB2 nanoparticles. The results indicate that nanoparticles play distinctive roles during coupled processes. At a lower temperature, ruptures Al2O3 film and refine microstructure morphology. Above solutionizing point, Zn proceeds deeply into matrix, partially block diffusion path to increase gradient. TiB2-regulated is respon...
