A group of researchers has developed a specialized aluminium alloy powder for Directed Energy Deposition (DED) Additive Manufacturing, published in the International Journal of Extreme Manufacturing. Produced by Amazemet in Poland, this alloy features an ultra-fine microstructure and low residual stress levels, enhancing mechanical performance.
When compared to AlSi10Mg, the new alloy shows a 70% increase in yield strength and a 50% increase in ultimate tensile strength, attributed to dispersion strengthening and grain refinement. The study highlights a reduced freezing range of 2.8°C, minimizing residual stresses and potentially reducing cracking risks during DED processes. This innovation could lead to greater adoption of DED technology across sectors like biomedical and energy.
