Provided is a method of producing a composite having high strength and high thermal conductivity. The method includes: an alloy preparation step including preparing an alloy which is a solid solution containing α-Fe as a solvent and at least one type of α-phase stabilizing element as a solute; a first mixing step including mixing at least one type of α-phase stabilizing element in powder form and SiC to prepare a first mixture; a second mixing step including mixing the alloy and the first mixture to prepare a second mixture; and a sintering step including sintering the second mixture.

Method for manufacturing αFe—SiC composite material, and αFe—SiC composite material

Provided is a Fe-based sintered body which has both of a high hardness and a high thermal conductivity and which can be more stably produced. The Fe-based sintered body includes: a matrix () containing Fe as a main component; and a hard phase () dispersed in the matrix (). The matrix () is formed in a network shape and contains αFe. The hard phase () contains TiC.

Fe-based sintered body, Fe-based sintered body production method, and hot-pressing die

Provided is a solder material that has a high melting point and exhibits superior mechanical characteristics, and therefore can form a connecting portion with high heat-resistant reliability.
