Abstract
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).
Claims25
A method of joining, comprising:
- rupturing an outer shell of one or more undercooled liquid metallic core-shell particles under ambient conditions, each core-shell particle having an undercooled liquid metallic core material contained within the outer shell to release the undercooled liquid metallic core material;
- and
- solidifying the released undercooled liquid metallic core material under ambient conditions to join components that comprise at least one of a metallic material and a non-metallic material.
