Novel aluminum powder alloys with graded density are studied by differential scanning calorimetry, x-ray diffraction, fractographic, and x-ray phase analyses. The influence of solution treatment and aging on the microstructure and properties of the alloys is investigated. The variation of properties over the thickness of the specimens is determined. It is shown that the mechanical properties are the best after a 2-h solution treatment at 495°C and subsequent 8-h aging at 190°C with air cooling.
