  • 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.

  • HOLLOW MEMBER AND METHOD FOR FORMING HOLLOW MEMBER
    Publication number: 20140174610
    Abstract: A tubular hollow member to which torsion about a center line is applied is characterized in performing a partial heat treatment on part of a peripheral wall of the hollow member to make the hardness of an outer portion of the peripheral wall greater than the hardness before heating and greater than the hardness of an inner portion of the peripheral wall, and reduce a residual stress of the inner portion of the peripheral wall.
