On the machinability of selective laser melted duplex stainless steels

Duplex stainless steels are well known for their high corrosion resistance, strength, and other useful characteristics, but mainly suffer from a lack of machinability. Selective laser melting, one of the additive manufacturing technologies was recently shown to be suitable for processing duplex stainless steels. However, the point-by-point consolidation of the powders and the complex thermal variations convert the biphasic ferrite plus austenite...
