Aspects of the disclosure are directed to forming a three-dimensional (3D) structure by depositing an alloy composition on a target, and solidifying portions of the alloy composition to form the 3D structure. The solidifying includes producing a martensitic structure by destabilizing a ferrite phase of the alloy composition while solidifying the alloy composition.

An example system may include a material source and a substrate having a molten pool on a surface of the substrate, wherein the molten pool faces a downward direction defined with respect to gravity. The system may include a computing device. An example technique may include, by the computing device, controlling the material source to direct a stream of solid material to the molten pool in an upward direction defined with respect to gravity. The material combines with the molten pool to form a deposited volume of a plurality of deposited volumes. The plurality of deposited volumes defines a component. An example computer readable storage medium may include instructions that, when executed, cause at least one processor to control, based on a digital representation of the component, an energy source to direct an energy beam at the substrate to form the molten pool, and control the material source.
