Process optimization and mechanical properties of oxide dispersion strengthened nickel-based superalloy by selective laser melting

Oxide dispersion strengthened nickel-based superalloy (ODSN) is widely used in structural materials such as aerospace and nuclear industry, but its uniform dispersion distribution of particles makes it only necessary to manufacture using conventional powder metallurgy technique. Selective laser melt...
