“…The hardness profiles were measured along middle line and ±2 mm from the middle line on the cross section. Sillapasa et al showed higher hardness in the advancing side (A-side) than in the retreating side (R-side) in the friction stir welds of 6N01 Al alloy [21]. However, the hardness was symmetric on both sides in the present cast Al alloy.…”

Abstract:Various heat input conditions and post-weld heat treatments were adopted to investigate the microstructure evolution and mechanical properties of tungsten inert gas (TIG) welded joints of AA6082-T6 with porosity defects. The results show that the fracture location is uncertain when an as-welded joint has porosities in the weld zone (WZ), and overaging in the heat-affected zone (HAZ) at the same time. When the fracture of the as-welded joint occurs in the HAZ, the total heat input has a linear relation with the tensile strength of the joint. An excess heat input induces the overgrowth of Mg 2 Si precipitates in HAZ and the coarsening of α-Al grains in WZ, resulting in a decrease in the microhardness of the corresponding areas. After artificial aging treatment, the tensile strength of the welded joint is increased by approximately 9-13% as compared to that of as-welded joint, and fracture also occurs in HAZ. In contrast, for solution treated and artificial aging treated joint, fracture occurs suddenly at the rising phase of the tensile curve due to porosity defects throughout the weld metal. Furthermore, the eutectic Si particles of WZ coarsen and spheroidize after solution treatment and artificial aging treatment, due to the diffusion of Si to the surface of the original Si phases when soaking at high temperature.

“…At higher fatigue load aluminium alloy (7050) [19] has better fatigue strength than aluminium alloys (6N01) [20], (5754) and (5052-H32) respectively. Moreover, the curve of aluminium alloy skin (5754) is located symmetrically between the aluminium alloy curves 7050 (upper bound) and 5052 (lower bound).…”
