1. A method for forming a three-dimensional (3D) structure, the method comprising: depositing an alloy composition on a target, including adding a destabilizing component to the alloy composition that destabilizes the formation of ferrite during cooling; and solidifying portions of the alloy composition to form the 3D structure, including producing a martensitic structure having a volume that is 90-100% martensite by using the destabilizing component to destabilize the formation of a ferrite phase of the alloy composition while solidifying the alloy composition.
