Many engineering applications demand materials with hard surface and tough core. In the present study, the enhancement of this combination of properties was achieved in aluminium alloy AA6061 by Severe Surface Mechanical Treatment (SSMT). The process parameters were optimized using Taguchi L9 orthogonal design of experiments. The size of shots, speed of revolution of shaft and duration of treat...

This study investigates the wear resistance of four AA6061 MMCs together with the monolithic AA6061 alloy, all in the T6 condition, using a pin-on-disc test. In addition to the widely studied 20 vol.% Saffil MMCs, the present investigation considered a hybrid of 11% Saffil + 20% Sic, and a high volume fraction Sic, MMC. AA6061 + 60% Sic,. The wear behaviour against P400 Sic grit adhesive bonded...

The current work is concerned with the synthesis of aluminium (AA6061-T6) matrix composites (AMCs) reinforced 15 and 20 weight percentages silicon nitride (Si3N4) particulates using indigenously fabricated electric stir casting furnace bottom discharge arrangement. major concern in AMCs ceramic particles wettability route, it was overcome by adding 2% magnesium melt, proper incorporation time, ...

Meltless recycling technique has been utilized to overcome the lack of primary resources, focusing on reducing the usage of energy and materials. Hot press was proposed as a novel direct recycling technique which results in astoundingly low energy usage in contrast with conventional recycling. The aim of this study is to prove the technical feasibility of this approach by characterizing the rec...

Abstract The major problem confronting aluminium alloy in various fields of engineering is based on the structural and continual failure a component service. difficulties encountered are resolved through addition RHA as strengthening agent to metal matrix composite. fabrication MMC (AA6061/RHA) using metallurgical stir casting route array 2, 4, 6 8 wt. % was done. Polarization test carried out ...

Abstract In this research, an effect of low temperature on the mechanical properties and microstructure 6061-T6 aluminium alloy (AA6061-T6) subjected to static dynamic loading was investigated systematically. The specimens were compression at − 80°C in a range strain rates from 0.001 0.1 1/s under conditions, 1250 3400 conditions compare their responses. deformation mechanisms discussed based E...

Surface finish and surface hardness of the components play vital role in quality of products/components, in general and failure resistance, in particular. One of the finishing process that involve surface plastic deformation and introduces compressive residual stresses and thereby improve fatigue resistance is “Burnishing”. Even though the burnishing process is widely employed, its process para...

in the present study, mechanical properties and low cycle fatigue behavior of a solid-solutionized aa6061 aluminum alloy produced by equal channel angular pressing (ecap) process were investigated. the grain refinement after two passes of ecap significantly increased the yield stress and ultimate tensile stress and decreased the ductility of the alloy. however, the improvement of low cycle fati...
