Abstract:
Spark Plasma Sintering technology is widely used to develop new materials with a fine and controlled microstructure. The key stage in its development (i.e. industrialisation) is the mastering of scale-up. From a SPS perspective, this requires suitable graphite tooling and a sintering cycle that can be applied to large parts. Samples with 60 mm diameter and 10 mm height were sintered from an aluminium alloy powder and characterised to determine the sintering conditions. Then, samples with 170 mm diameter and 15 mm height were sintered. Their metallurgical characterisations, including the numerical simulations of the sintering process, were performed to determine the effects of the scale-up and, at the end, to optimize the sintering conditions to obtain dense and homogeneous samples.
