Publication number: 20140370322Abstract: A sintered structure and method for forming it are disclosed. The method includes obtaining core-shell particles having a core material and a shell material, forming the particles into a powder compact, and annealing the powder compact at an annealing temperature. The shell material is a metal that diffuses faster than the core material at the annealing temperature and diffuses to the contacts between the core-shell particles during annealing to form sintered interfaces between the core-shell particles. The sintered structure can have discontinuous regions of shell material between the sintered interfaces. The core material can be a metal, semiconductor or ceramic. The core material can be copper and the shell material can be silver. The sintered interfaces can be almost purely shell material. The annealing temperature can be significantly lower than the temperature needed to form interfaces between particles of the core material without the shell material.Type: ApplicationFiled: June 17, 2013Publication date: December 18, 2014Inventors: Carol Anne Handwerker, Suk Jun Kim, Eric A.
