Aluminum alloys 7075 (Al 7075) are widely used for various industrial components in which machining operations often conducted during their manufacturing process. However, the could introduce defects on machined surfaces of will be carried over and may lead to either issues subsequent fabrication process or failure products' service life. This study investigates surface's Al underwent drilling ...

A technique for fatigue life prediction of metals is presented based on a microstructure-sensitive estimation plastic strain energy per cycle. The approach enables rapid temperature evolution, cyclic energy, and fracture entropy. Theoretical experimental results are low-carbon steel 1018 aluminum 7075-T6 specimens. It shown that the realistically predicts metallic

Abstract Composite coatings were prepared by using epoxy-hardener having a 2:1 composition and functionalized SiO 2 0, 0.01, 0.03, 0.05 proportion/s accordingly. Curing of the on aluminium alloy 7075 substrates was performed at temperature 60 ± 5 °C. Moreover, corrosion assessment carried out in 0.6M NaCl solution room temperature. The outcome Fourier Transform Infrared Spectroscopy (FT-IR) con...

This paper introduces an experimental technique to investigate dynamic friction characteristics of sliding interfaces at normal pressures up to 125 MPa, slip speeds up to 15 m/s and slip distances of approximately 10 mm. This new apparatus involves a novel modification of the conventional torsional Kolsky bar apparatus employed extensively in the past to investigate high-strain-rate behavior of...

Aluminium matrix composites (AlMCs) of AA7075 aluminium alloy reinforced with 0.5 and 1 wt.% multiwall carbon nanotubes (MWCNTs) were fabricated powder metallurgy techniques using three different mechanical milling strategies, varying the energy stage in which reinforcements added to pre-alloyed powders. In this paper, we focus on influence these parameters dispersion MWCNTs. Characterization o...
