Technical basis of using laser direct energy deposition as a high-throughput combinatorial method for DC-cast Al-Mn alloy development

This work evaluated the technical basis of using laser direct energy deposition (DED) additive manufacturing (AM) as a rapid alloy screening method to study the phase transformation of second phase particles and recrystallization behavior of Al-Mn alloy AA3104 throughout the steps of thermomechanica...
