    • 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.
    • 公开了一种烧结结构及其形成方法。 该方法包括获得具有芯材料和壳材料的核 - 壳颗粒,将颗粒形成粉末压块,并在退火温度下对粉末压块进行退火。 外壳材料是在退火温度下比核心材料更快地扩散的金属,并且在退火期间扩散到核 - 壳颗粒之间的接触处以在核 - 壳颗粒之间形成烧结界面。 烧结结构可以在烧结界面之间具有壳材料的不连续区域。 核心材料可以是金属,半导体或陶瓷。 核心材料可以是铜,壳材料可以是银。 烧结界面几乎可以是纯外壳材料。 退火温度可以显着低于在没有壳材料的情况下在芯材料的颗粒之间形成界面所需的温度。
