One of the major challenges in welding aluminium (Al) alloys and steels is growth brittle intermetallic phases, which depends on thermomechanical processing history alloying elements. This work focuses phase layers formed roll bonded composites Al alloy 6082 stainless steel 316L after interdiffusion at temperatures range 400 – 550 °C. Scanning transmission electron microscopy characterisation s...

A uniform source-and-sink (USS) scheme, which combines features of the reverse [F. Müller-Plathe, J. Chem. Phys. 106, 6082 (1997)] and improved relaxation [B. Y. Cao, J. Chem. Phys. 129, 074106 (2008)] methods, is developed to calculate the thermal conductivity by nonequilibrium molecular dynamics (NEMD). The uniform internal heat source and sink are realized by exchanging the velocity vectors ...

The aim of the present research is to investigate the fatigue behaviour of friction stir (FS) welded tubular joints in aluminium alloy subjected to torsional fatigue loading. To manufacture the samples which were tested, an MTS I-STIR process development system was equipped with a retracting tool specifically designed for these tubular welds. Al 6082-T6 FS welded samples were tested under cycli...

Friction drilling is a hole-making process suitable for thin sections of ductile metal. A rotating tool plunged into the workpiece to form pilot hole. The hole then threaded in follow-up process. bushing forms on exit side hole, which allows longer engagement lengths assemblies. For comparison purposes, four combinations threaded-hole processes were applied 1.5 mm-section, 6082-T6 aluminium all...

The age hardening process of a 6082 Al–Mg–Si alloy by isothermal ageing at 100, 125 and 150 °C for 0 to 40 days has been investigated by both conventional and high-resolution transmission electron microscopy. Changes in sizes and densities of the pre-β and β phases during ageing can explain the evolution of hardness, in particular a plateau in the curve of the hardness versus ageing time. Fully...
