摘要： A sintered material excellent in thermal stress and bonding strength; a connection structure containing 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 has a base portion, buffer portions, and filling portions. The buffer portions and filling portions are dispersed in the base portion. The base portion is a metal sintered body, each buffer portion is formed from a pore and/or material that is not the same as the sintered body, and each filling portion is formed from particles and/or fibers. The sintered material satisfies A>B. A is the kurtosis of volume distribution of the base portions in a three-dimensional image of the sintered material. 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.

摘要： A magnetic structural body contains core-shell structure particles each including a core section and a shell section covering the surface of the core section. The core section is made of an alloy containing a first metal and a second metal. The shell section is made of an alloy which contains the first metal and the second metal and which has a first metal-to-second metal content ratio different from that of the core section. The first metal is a magnetic metal and has a standard redox potential higher than that of the second metal. The neighboring core-shell structure particles are linearly linked to each other.

摘要： Proposed is a nitinol nanofiber with an average surface roughness that is enhanced through mechanical and chemical treatments. The enhanced surface roughness improves biocompatibility and promotes tissue growing, thereby improving the bioavailability of the nitinol nanofiber. The nitinol nanofiber undergoes infrared irradiation whereby the nitinol fiber exhibits improved tensile strength, elastic modulus, and maximum restorative stress. Therefore, fatigue fraction does not easily occur in the nitinol fiber even when the nitinol nanofiber has a constant roughness. The present invention provides bio-use or medical nitinol nanofibers that are highly biocompatible.
