Autor: Armando Yáñez, J.M. Amado, M.J. Tobar, José-María Montero

Publikováno v: Physics Procedia. 83:606-612

Water atomized and gas atomized powders are commonly used in 3D laser manufacturing. Both types of AISI 316L stainless steel powders are available which differ in their manganese content. This is due to specific procedures related to the two differen
