Publication number: 20230383388Abstract: Undercooled liquid metallic core-shell particles, whose core is stable against solidification at ambient conditions, i.e. under near ambient temperature and pressure conditions, are used to join or repair metallic non-particulate components. The undercooled-shell particles in the form of nano-size or micro-size particles comprise an undercooled stable liquid metallic core encapsulated inside an outer shell, which can comprise an oxide or other stabilizer shell typically formed in-situ on the undercooled liquid metallic core. The shell is ruptured to release the liquid phase core material to join or repair a component(s).Type: ApplicationFiled: April 17, 2023Publication date: November 30, 2023Inventors: Martin Thuo, Ian Tevis

Publication number: 20230286046Abstract: A system and method are presented for producing metallic core-shell particles. The system includes the housing having a hollow interior configured to receive and hold a molten metal input, a carrier fluid, and one or more reagents. The system also includes a shearing assembly positioned within the hollow interior of the housing. The shearing assembly is configured to, when the molten metal input, carrier fluid, and one or more reagents are held within hollow interior and sealed within housing, shear the molten metal input into particles of an effective size so that a shell created on a surface of the particles via reaction with the one or more reagents prevents a core of the particles from solidifying when the particles are cooled to a temperature below a freezing temperature of the molten metal input.Type: ApplicationFiled: March 30, 2023Publication date: September 14, 2023Inventors: Martin Thuo, Ian Tevis, Chris Frankiewicz

Publication number: 20230182236Abstract: A material includes a plurality of supercooled micro-capsules each including a metallic core in a liquid state at a temperature below a solidification temperature of the metallic core and further includes a metallic shell surrounding each respective metallic core. A plurality of alloyed metallic particles and flux are mixed with the plurality of supercooled micro-capsules to form a solder paste. Upon heating the solder paste, the plurality of alloyed particles melt. As the metallic shells destabilize, the liquid metallic cores interdiffuse with the melted alloyed particles forming a new alloy that has a higher melting temperature than the melting temperature of the alloyed metallic particles.Type: ApplicationFiled: December 13, 2022Publication date: June 15, 2023Applicant: SAFI-Tech, Inc.Inventors: Martin Thuo, Ian Tevis, Dana Drochner
