Abstract: Aspects of the disclosure are directed to methods and/or apparatuses involving the formation of pore-free or nearly pore-free liquid droplets. As may be implemented in accordance with one or more embodiments, liquid droplets including metal are formed having pores within the liquid droplets. This may involve, for example, atomizing liquid metal with a gas and forming the droplets having pores. The pores are then driven out of the liquid droplets by heating the liquid droplets from a first state in which an outer surface of the droplets has a lower temperature than an inner region thereof, to a second state in which the outer surface has a higher temperature than the inner region.

Abstract: Aspects of the disclosure are directed to powder spreading and an apparatus therefor. As may be implemented in accordance with one or more embodiments, an apparatus having a flexible core and a shell on a surface of the core is used to displace powder in a powder bed. The shell has a low coefficient of friction, for example on the order of 0.10, and may operate to conduct static electricity away from the powder. The shell may be engaged with the powder to displace the powder and form a uniform powder layer having a planer upper surface, as the core is advanced across the powder bed.

Abstract: Solid immiscible alloys and methods for making the solid immiscible alloys are provided. The microstructure of the immiscible alloys is characterized by a minority phase comprising a plurality of particles of an inorganic material dispersed in a majority phase comprising a continuous matrix of another inorganic material. The methods utilize nanoparticles to control both the collisional growth and the diffusional growth of the minority phase particles in the matrix during the formation of the alloy microstructure.
