Additive manufacturing of alloys with programmable microstructure and properties

Nature Communications, 2023
In metallurgy, mechanical deformation is essential to engineer the microstructure of metals and to tailor their mechanical properties. However, this practice is inapplicable to near-net-shape metal parts produced by additive manufacturing (AM), since it ...
