In situ design of advanced titanium alloy with concentration modulations by additive manufacturing

Fine-scale strengthening swirls Creatively combining different alloys using additive manufacturing methods has the potential to produce materials with interesting properties. Zhang et al . use laser powder bed fusion to combine small amounts of 316L stainless steel into Ti64 titanium alloy. This process creates an alloy with a distinctive microstructure that retains high strength while substantially improving ductility. The design strategy should be useful for improving mechanical properties in other alloy system as well. —BG
