  • Fe-based sintered body, Fe-based sintered body production method, and hot-pressing die
    Patent number: 11858045
    Abstract: 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 (1) containing Fe as a main component; and a hard phase (4) dispersed in the matrix (1). The matrix (1) is formed in a network shape and contains ?Fe. The hard phase (4) contains TiC.
