Abstract
The effect of solution temperature and quench delay on the microstructure and mechanical properties of an extruded Al-Mg-Si-Cu-Mn alloy was investigated by employing differential scanning calorimetry, transmission electron microscopy, hardness test, and tensile test. The extruded specimens were held at 500 and 540 ^oC, respectively, for 80 min for solutionizing..... More

Abstract
In this study, the Vickers hardness of precipitation-strengthened Al-Sc-X (X = Zr, Si, and Fe) alloys were predicted using machine learning models, depending on the alloys’ compositions, solid-solution treatment and aging conditions. The data used for machine learning were collected from the literature. Among the models, tree-based ensemble models such..... More

Abstract
The elevated temperature strength of multicomponent Al-Si alloys is greatly affected by the volume fraction and the interconnectivity of hard phases formed upon solidification. In the present investigation, such influences were examined for two Al-Si-Cu-Ni alloys with different total volume fractions of hard phases. To control the microstructural features related..... More

Abstract
The effects of heat treatment conditions on the mechanical properties and energy absorption capacity of 7003 (Al-6Zn-0.6Mg) aluminum alloy were studied. The extruded material was heat treated at various temperatures to prepare annealed or aged specimens. Tensile tests, hardness measurements, electron backscatter diffraction characterizations, and differential scanning calorimeter analyses were..... More

Materials Analysis & Characterization

Abstract
Experimental techniques for serial sectioning and reconstruction were investigated in the three-dimensional imaging of microstructures in metallic materials. Mechanical polishing equipped with a light optical microscope and a digital image processor was used for the serial sectioning and reconstruction. Different processing conditions were investigated for three different alloys: Al-Si alloy,..... More
