Design of a Cobalt-Free Maraging Steel with Ultra-High Strength of 2.3 GPa Through Additive Manufacturing. [PDF]

Adv Sci (Weinh)
A computationally designed, cobalt‐free maraging steel tailored for additive manufacturing achieves an ultra‐high tensile strength of 2.3 GPa with 5.7% elongation. This exceptional strength‐ductility synergy stems from high‐density core‐shell Ni3Ti/NiAl nanoprecipitates, a crack‐resistant composition, and a fine equiaxed grain structure enabled by ...
