Void growth in 6061-aluminum alloy under triaxial stress state
In numerous metals and alloys, ductile fracture involves void nucleation, growth, and coalescence. In this contribution, void growth has been quantitatively characterized in an extruded 6061-wrought Al-alloy as a function of stress state in notch tensile test specimens. Digital image analysis and Stereology have been used to estimate the volume fraction and three-dimensional number density of v...
متن کاملWelding Aluminum Alloy 6061 with Opposing Dual Torch Gtaw Process
Cracking is a major concern in welding aluminum alloys. Although weld solidification cracks can be eliminated through addition of filler alloy, the additives modify the alloy or base-metal constituents and may not always be desirable. High-energy beam processes, such as electron-beam welding, that result in minimal heat input reduce crack sensitivity, but their high cost limits their applicatio...
متن کاملStress-Assisted Corrosion of Aluminum 6061 in Basic Solution
Caustic stress corrosion cracking has only been superficially examined in aluminum alloys. In caustic (basic) environments, the inherent, protective oxide layer becomes soluble on aluminum and allows for further degradation. The purpose of this study is to observe the effect of a strong base solution (sodium, hydroxide, sodium hypochlorite, sodium silicate, pH ~12) on the strength and stress-st...
متن کاملTwo-dimensional Mapping of Residual Strains in 6061-t6 Aluminum Alloy Friction Stir Welds
The residual strain profiles were measured through the thickness of friction-stir welded (FSW) plates using neutron diffraction to study the relationship between the angular distortion and the residual strain distribution. Three different weld specimens were prepared from a 6061-T6 aluminum alloy with the purpose of separating the effects of the frictional heat and plastic deformation on the re...
