Effects of annealing on the microstructure and mechanical properties of selective laser melted AlSi7Mg alloy

Selective laser melting, due to the high energy density input and the small interaction time (106 K/s), can result in an ultrafine microstructure and excellent mechanical properties. However, due to the nonuniform nature of the temperature distribution and the transition from liquid to solid, high r...
