Advanced Engineering Materials, EarlyView.This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Numerical simulation of tridimensional electromagnetic shaping of liquid metals
, 1992 We describe a numerical method to compute free surfaces in electomagnetic shaping and levitation of liquid metals. We use an energetic variational formulation based on the total energy and we apply optimization techniques to compute a critical point. The
