Advances in Materials Science and Engineering, Volume 2021, Issue 1, 2021., 2021 The aim of this research paper is to find the wear behaviour of Al7075 MMCs. In this investigation, the wear tests on the as‐cast and age‐hardened specimens were performed on an advanced rotary tribometer. The materials selected for the analysis are Al7075 as a matrix, and the reinforcements are boron carbide.

Design and Numerical Simulation of Pyramidal Prefolded Patterned Thin‐Walled Tubes
Advances in Materials Science and Engineering, Volume 2021, Issue 1, 2021., 2021 An improved pyramidal prefolded pattern was designed and applied to thin‐walled tubes. This delicately designed pattern modularizes the tube to control the folding process and act as an inducer to trigger deformation modes with outstanding crushing performance.

Friction influence on the AA6060 aluminium alloy formability
Frattura ed Integrità Strutturale, 2019 Using a finite element calculation code, this work analyses the influence of friction during a stamping test conducted on the AA6060 aluminium-based alloy. The study focuses on phenomena happening when the sheet necking appears. This condition, based on the Hill’s localized necking theory and the Swift’s diffuse necking theory, is dependent on the ...

Behaviour and modelling of aluminium alloy AA6060 subjected to a wide range of strain rates and temperatures [PDF]
EPJ Web of Conferences, 2015 The thermo-mechanical behaviour in tension of an as-cast and homogenized AA6060 alloy was investigated at a wide range of strains (the entire deformation process up to fracture), strain rates (0.01–750 s−1) and temperatures (20–350 ∘C). The tests at strain rates up to 1 s−1 were performed in a universal testing machine, while a split-Hopkinson tension ...

On the Folding Mechanics of Square Columns with Double‐Surfaced Gradients
Mathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019 The implementation of graded thicknesses in structural designs is an efficient strategy for improving the energy absorption performance of thin‐walled columns. In this study, the mechanical responses of square columns with double‐surfaced gradients under axial crushing forces were analytically and numerically investigated. A mathematical expression for

Buffering Performance of High‐Speed Impact Space Penetrator with Foam‐Filled Thin‐Walled Structure
Shock and Vibration, Volume 2019, Issue 1, 2019., 2019 High‐speed penetrators carrying detection equipment impact planetary bodies at high speeds, and they are therefore buried at depths of up to several meters beneath the surface. During the friction and collision with the crust of the planet, the acceleration of the scientific instrumentation is significantly large. The vibration protection structure for

Recrystallization in a Hot Deformed Al‐Mg‐Si Alloy: The Effect of Fine Precipitates
Texture, Stress, and Microstructure, Volume 35, Issue 2, Page 55-70, 2002., 2002 The recrystallization of an Al‐Mg‐Si alloy deformed by plane strain compression at 400°C and 1 s-1 has been studied. Fine particles are found to have a significant influence on the development of recrystallization textures. Annealing at 400°C, in the presence of Al‐Fe‐Si particles located on boundaries, results in a weak recrystallization texture ...
