Notes:
A new approach is explored to achieve sintered aluminium alloy from metallic powdermixtures without compression or adding Mg. In this approach, mixtures of micron-sized aluminiumpowder (average size of 2.5 μm) and nano-sized alloying elemental powder of Cu and Sn (less thanof 70nm), at appropriate proportions to compositions of Al-6wt%Cu, Al-6wt%Cu-3wt%Sn with andwithout adhesive binder were prepared by magnetic stirring. Then, the powder mixture was pouredinto a crucible and heat treated at a temperature of 600°C for 11 hours in inert atmosphere of N2 orAr. In this paper, we investigate the debinding behavior of loosely packed Al-based powder mixtureand the microstructural development and mechanical property sintered parts using a combination ofthermogravimetric analysis (TGA), differential scanning calorimetry (DSC), X-ray diffractrometry(XRD) and hardness test
