Abstract Scope |
Multi-metals additive manufacturing (AM) is an emerging research underpinning numerous technologies including AM repair of dissimilar metals and in-situ alloying. Understand the fluid dynamics of multi-metals powders and laser using powder-bed AM as a function of AM process parameters through a high-fidelity multi-physics modelling rationalises the multi-metals thermal-solutal-fluid flow and allows the link between composition and flow science to be constructed. The results provide insights into elemental powder AM and in-situ alloying of NiAl, NiTi and TiAl binary metals. The melt flow dynamics is characterised by dimensionless Reynolds (Re) and Péclet (Pe) numbers. The mass loss rate has been found to be governed by the Re with a simple proportional correlation linked with AM process behaviour. In in-situ binary alloying, convective mixing further complicates the mass loss and flow dynamics. The novel materials-process design developed will lead to AM design of optimum final product composition and mitigation of defect formation. |
