Ageing Process of Al-Cu-Mg Alloy

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

Effect of Creep Aging Process on Microstructures and Properties of the Retrogressed Al-Zn-Mg-Cu Alloy

The creep aging behaviors of retrogressed Al-Zn-Mg-Cu alloy were studied by uniaxial tensile creep tests at 140 ◦C. The effects of creep aging time and applied stress on microstructures and properties of the studied alloy were investigated by using transmission electron microscope (TEM), hardness, and corrosion resistance tests. Results show that the effects of the creep aging process on micros...

Application of uniform design in optimisation of three stage ageing of Al-Cu-Mg alloys

The hardness variation and the behaviour of precipitation during the process of three stage ageing of three Al-Cu-Mg alloys were investigated using micro-hardness and differential scanning calorimetry (DSC). To facilitate the determination of the optimised heat treatment condition, a uniform design method was employed by which the influences of three stages interrupted ageing on the hardness an...

FRACTIONAL RECRYSTALLIZATION KINETICS IN DIRECTLY COLD ROLLED Al-Mg, Al-Mg-Sc AND Al-Mg-Sc-Zr ALLOY

The evaluation of texture as a function of recrystallization has been characterized for directly cold rolled Al-6Mg, Al-6Mg-0.4Sc and Al-6Mg-0.4Sc-0.2Zr alloys. Samples were annealed isothermally at 400 °C for 1 to 240 minutes to allow recrystallization. Recrystallization kinetics of the alloys is analyzed from the micro-hardness variation. Isothermally annealed samples of aluminum alloys were ...
