“…Also higher joint strength can be achieved as the penetration depth of the tool pin in friction stir welding of the aluminum alloy is increased (Uzun et al, 2005). When FSW is applied to high load bearing components then joint strength is a critical parameter and must be improved as per previous reports (Kim & Jang, 2006;Khorrami et al, 2012;Cavaliere, 2013;Rajakumar et al, 2011;Aliha et al, 2016). The effect of tool geometry on the welding strength is an important factor to study.…”

In the present experimental study, two dissimilar sister aluminum alloys, 5083 and 5086, are welded through friction stir welding process. Different experiments are conducted on vertical milling machine through a fixture design and firm holding welding plates on it. These experiments are performed by varying welding parameters including welding speed, rpm, different pin profiles, tool tilt angle at five levels each. Two different mechanical properties of the welded specimen (i.e. tensile strength and percentage of elongation) have been tested and compared with the base metals to find out the joint efficiency. Also it is observed that rpm, tool tilt angle and different pin profiles make significant impacts on friction stir welded joints. Tool rpm increases the tensile strength to an extent. Also, tool pin profile affects the stirring or plastic flow of material under tool shoulder. It is shown through visual and optical analysis that surface finish and weld quality of joints depend on tool tilt angle.

Temperature-time-property (TTP) curves for aluminum alloy 6082 were acquired by an interrupted quenching method. The TTP curves presented a ''C''-shape and the critical temperature range was 240-440°C with temperature at the nose of the C-curve of approximately 335°C. At this temperature, the greatest rate of second phase development and the largest, and most rapid, drop in hardness was observed. The change was approximately 50% of the maximum when isothermally held or 50 s. Microstructural evolution of the quenched aluminum alloy 6082 was analyzed with a transmission electron microscope (TEM). TEM analysis results showed that secondary phase particle growth rate was controlled by diffusion. Growth was rapid during the critical temperature range. When the holding time was prolonged, the spherical and needle-shaped precipitates, which provided a significant strengthening effect, rapidly transformed into coarse, rodshaped precipitates. This over-aged condition resulted in loss of the precipitate strengthening effect.
