CORROSION – BUCKLING INTERACTION OF 6061-T4 AL ALLOY FIXED – PINNED COLUMNS – EXPERIMENTAL STUDY

Buckling of liquid columns.

Under appropriate conditions, a column of viscous liquid falling onto a rigid surface undergoes a buckling instability. Here we show experimentally and theoretically that liquid buckling exhibits a hitherto unsuspected complexity involving three different modes-viscous, gravitational, and inertial-depending on how the viscous forces that resist bending of the column are balanced. We also find t...

Effect of Modified AA 5356 Filler on Corrosion Behavior of AA 6061 Alloy GTA Welds

The corrosion behavior of the fusion zone of gas tungsten arc (GTA) welds of AA6061 alloy was studied. Role of gas tungsten arc welding techniques such as continuous current (CC) and pulsed current (PC) and reference filler (AA5356) were studied. Role of different grain refiners such as scandium, zirconium and Tibor in the reference filler was studied. Dynamic polarization testing was used to d...

CORROSION BEHAVIOUR OF Al-Li-Cu-Mg ALLOY 8090-T651

Influence of TiC particulate reinforcement on the corrosion behaviour of Al 6061 metal matrix composites

Aluminum matrix composites (AMCs), reinforced with ceramic particulates, have significant applications in the field of aerospace, marine, automobiles, sports and recreation. Al-TiC particulate composite has better potential for high-temperature applications. The corrosion behaviour of Al 6061-TiC particulate composites prepared by stir casting route, has been explored in chloride medium using e...

The effects of maintaining temperature in annealing heat treatment for an FSWed 6061-T6 Al alloy.

The technological development of all kinds of lightweight transportation devices including vehicles, aircraft, ships, etc. has progressed markedly with the demand for energy saving and environmental protection. Aluminum alloy is in the spotlight as it is a suitable environmentally friendly material. However, deformation is a major problem during the welding process because aluminum alloy has a ...
