SINTERED MATERIAL, CONNECTION STRUCTURE, COMPOSITE PARTICLE, JOINING COMPOSITION, AND METHOD FOR MANUFACTURING SINTERED MATERIAL
20200001366 · 2020-01-02 · ·

Provided are a sintered material excellent in both thermal stress and bonding strength; a connection structure comprising the sintered material; a composition for bonding with which the sintered material can be produced; and a method for producing the sintered material. The sintered material comprises a base portion, one or more buffer portions, and one or more filling portions. The buffer portions and the filling portions are dispersed in the base portion. The base portion is a metal sintered body, each buffer portion is formed from at least one of a pore and a material that is not the same as that of the sintered body, and each filling portion is formed from at least one of particles and fibers. The sintered material satisfies A>B, where A is the kurtosis of volume distribution of the base portions in a three-dimensional image of the sintered material, and B is the kurtosis of volume distribution of the base portions in a three-dimensional image of the sintered material from which the filling portions are removed.
