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).
Claims15
A metallic matrix comprising:
- a product of solidification of a liquid metal or alloy having a melting point in the range of 62° C. to 250° C.;
- and
- shell fragments comprising an oxide of the metal or alloy, wherein the shell fragments are fragments of an outer shell of one or more liquid metallic core-shell particles each comprising an undercooled liquid metallic core comprising the metal or alloy, and the outer shell on the undercooled liquid metallic core.
