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

Consumed energy is minimized to reduce running cost. Final formed products of uniform quality are successively obtained. High productivity is provided. A primary forming step of obtaining a primary formed product by plastically working a heated steel sheet with a primary forming die set for a predetermined time period, a secondary forming step of machining the primary formed product with the secondary forming die set for a predetermined time period to obtain a secondary formed product, and a hardening step of allowing a cooling die set placed in a hydraulic press controlled by a servomotor to hold the secondary formed product under pressure for a longer time period than the time period of each of the primary and secondary forming steps to obtain a hardened final formed product are successively performed in sequence. The hardening step is performed independently without coordinating with the primary and secondary forming steps.

Method for forming steel sheet by hot pressing

Fuel vapor is prevented from leaking to the outside during refueling, and even when an air space is formed in an upper portion of a fuel filler pipe, a diagnosis of leakage of fuel vapor can be performed with good accuracy. During refueling, fuel vapor is guided from a fuel tankto a canister, and is absorbed by the canister. A change in the internal pressure of a fuel vapor path including the fuel tank, a fuel vapor pipe, and the canisteris detected by a pressure sensor, thereby performing a diagnosis of leakage of fuel vapor. An upper spacein the fuel tankand an upper spacein a fuel filler pipecommunicate with each other through an airflow resistance pipe, and in order to restrict flow of fuel vapor from the fuel tankthrough the airflow resistance pipeinto the fuel filler pipeduring refueling, the airflow resistance pipeincludes an orifice
