Abstract At the moment, high production costs prevent friction stir welding (FSW) process from further industrial applications even if comparable fatigue strength of joints can be reached. Higher speed may reduce but decrease manufactured FSW joints. A potential solution is a mechanical post weld treatment directly after to increase joint again. In this study, hydrostatic deep rolling was appli...

The influence of nanoscale reinforcement on the mechanical behavior of ultrafine-grained composites was studied. Al 5083 (Al– 4.5 Mg–0.57Mn–0.25Fe) composites, with grain size of 115 nm and B4C reinforcement size of 38 nm, were fabricated via cryomilling and consolidation. The result reveals that the presence of nanoparticles enhances strength by interacting with dislocations, while simultaneou...

In this research, a finite element (FE) technique was used to predict the residual stresses in laser-peened aluminum 5083 at different power densities. A dynamic pressure profile create wave an explicit model, and stress results were extracted once solution stabilized. It is shown that as density increases from 0.5 4 GW/cm2, induced develop monotonically deeper 0.42 1.40 mm. However, with incre...

The paper deals with the optimization of welding parameters of friction stir welding of different Aluminium alloy groups. For this purpose 5 series Aluminium alloy Al 5083 and 6 series Aluminium alloy Al 6062 were taken .Tensile Strength test and micro structure analysis under various rotating speeds and tool profiles is conducted. It is observed that the increase in tool rotation speed and the...
