Magnetostructure material, and process for producing the same

A composite magnetostrictive material having a magnetostrictive performance required for a practical use and yet a higher strength. A composite magnetostrictive material 1 is comprised of a matrix 2 formed of a magnetostrictive material of an RM-based alloy, wherein R is a rare earth element and M is one of a transition metal and aluminum, and dispersion phases 3 dispersed in the matrix and formed of at least one of an RM-based metal, R and M.

Composite magnetostrictive material, and process for producing the same

A SmFe-based magnetostrictive material having an excellent magnetostrictive performance and an excellent mechanical strength provided by achieving a division of crystal grains. The SmFe-based magnetostrictive material includes boron (B) as an additive component, which contributes to the fine division of crystal grains. The content of boron (B) is set in a range of B.ltoreq.0.01% by weight.

A canister is provided for preventing the emanation of a vaporized fuel gas. The canister is capable of quickly heating the activated carbon through the resistance thereof up to a required temperature at the time of desorption of the vaporized fuel gas. The canister comprises a container having a vaporized fuel gas inlet port and an exit port. An aggregate of activated carbon is filled in the container to adsorb the vaporized fuel gas, and at least a pair of electrodes are provided for heating the activated carbon through the resistance thereof, at the time of desorption of the vaporized fuel gas. A highly electrically conductive activated carbon is used having an electric resistance of not larger than 500 .OMEGA./2.5.sup.3 cm.sup.3.

To the end of providing a fuel injector component such as a nozzle needle and a valve seat of a fuel injector for injecting fuel directly into a combustion chamber of a gasoline engine which has a sufficient durability and wear resistance even in the high temperature condition existing in the combustion chamber of the gasoline engine, the fuel injector component is made of a martensite stainless steel essentially consisting of 0.6 to 1.5% of C; 2.0% or less of Si; 1.0% or less of Mn; 10 to 18% of Cr; 1 to 6% of a member selected from a group consisting of Mo and Mo+(1/2)W; and a balance of Fe and inevitable impurities. The material may further comprise, in various combinations, 2% or less of V and/or Nb in terms of V+(1/2)Nb, 6% or less of Co, 3.5% or less of Cu, and at least one member of a group consisting of 0.2% or less of Pb, 0.05% or less of S, and 0.1% or less of Se.

A high cold-forging electromagnetic stainless steel comprises not more than 0.02 wt. % of C, not more than 0.50 wt. % of Si, not more than 0.50 wt. % of Mn, 10.0-18.0 wt. % of Cr, 0.30-1.50 wt. % of Mo, 0.05-0.50 wt. % of Ti, 0.30-2.00 wt. % of Al, 0.0005-0.05 wt. % of B, not more than 0.05 wt. % of N and the balance being substantially Fe. This steel may further contain a given amount of at least one of Nb, V, Pb, Ca, Se, S and REM. Such stainless steel is used as a material of parts in an electronically controlled fuel injection system.
