Abstract
Dissimilar AA6061 to AA7075-T6 joints fabricated by friction welding has been investigated to enhance the mechanical properties by post-weld heat treatment (PWHT) process. After fabrication, the welded samples are heat-treated by three different conditions namely, solution treatment, artificial aging and solution treatment followed by aging. Following this, the tensile properties and micro hardness of PWHT specimens were systematically investigated. Further, the influence of PWHT in fully deformed zone, partially deformed zone, heat affected zone, and parent metals were examined through the optical microscopy, scanning electron microscopy, transmission electron microscopy and energy dispersive spectrum. Finally, the results of PWHT specimens were discussed and compared with as-welded conditions.
