Abstract: Aspects of the disclosure are directed to additively manufacturing a three-dimensional structure. As may be implemented in accordance with one or more embodiments, a plurality of stacked layers are deposited, and for one or more respective layers of the plurality of stacked layers, pores are formed within the layer by applying pulsed energy to the layer. The pulsed energy is used to create a space sealed within the layer and having an inner surface defined by material of the layer.

Abstract: 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.
