Publication number: 20240066593Abstract: 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.Type: ApplicationFiled: August 23, 2022Publication date: February 29, 2024Inventors: Lianyi Chen, Ali Nabaa

Publication number: 20240024951Abstract: Aspects of the disclosure are directed to metal-based materials, their manufacture and their use. Certain embodiments involve providing powder in a metal-based foil/shell, and forming a tube from the foil/shell with the powder therein. The tube thus has a metal-based foil shell filled with the powder. Metal wire may be formed by rolling the tube filled with the powder and reducing the diameter of the tube. Certain embodiments are directed to the structure of such a tube prior to wire formation, and other embodiments are directed to the metal wire itself.Type: ApplicationFiled: July 25, 2022Publication date: January 25, 2024Inventors: Lianyi Chen, Jiandong Yuan

Publication number: 20230286212Abstract: 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.Type: ApplicationFiled: March 14, 2022Publication date: September 14, 2023Inventors: Lianyi Chen, Luis Izet Escano

Publication number: 20230028894Abstract: 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.Type: ApplicationFiled: July 16, 2021Publication date: January 26, 2023Inventors: Lianyi Chen, S. Mohammad H Hojjatzadeh, Qilin Guo
