The porosity is set in the range of 15 to 70%. In a manufacturing method for the carbon fiber reinforced composite material, a carbon fiber and a matrix are mixed, put in a metal mold, heated in the metal mold, and molded by hardening resin. As a method for mixing both sides, a method in which a carbon fiber and a matrix are stirred and mixed or a matrix is impregnated in a collective body of carbon fiber is used. As a molding method, a press molding in the range of 30 to 500kgf/cm is used. The resin hardening temperature is set in the range of 150 to 300 deg.C. Solid lubricant, adrasion resistant materials, or the like are added to the carbon fiber reinforced composite material as necessary.

ZrAl3 which is the nucleus for primary crystal aluminum is formed and solidification is begun uniformly from the die surfaces to the inside of the thickness by adding Zr to the alloy. The solidified aluminum crystals are, therefore, dispersed and the respective aluminum crystal spacings are made into the finally solidified parts, by which the cavities are dispersed.

摘要： PURPOSE:To manufacture the light alloy sintered member having excellent strength by subjecting a green compact of the powder of a high hardness light alloy in which, by heating, a metastable phase is transformed into a stable one via the generation of heat to hot plastic working in the intermediate temp. range of both phases or while the temp. is dropped to a phase transformation starting one after the generation of heat. CONSTITUTION:A green compact of the powder of a light alloy having the compsn. of Al85Ni5Y10 having a metastable phase with an amorphous structure is filled into a can made of an Al alloy, is heated to about 130 deg.C and is thereafter charged to a container heated to >=(a) point (287.2 deg.C), i.e., the phase transformation starting temp. The green compact is successively heated and, while the heat of >=50mJ/mg is generated at a point expressed by a peak on the way, is subjected to plastic working such as hot extruding into a bar-shaped sintered member. The phase transformation is perfectly completed at a (b) point (399.1 deg.C) to transform the phase in the structure into a stable one, by which the light alloy sintered member in which the coarsening of the crystalline structure in the alloy is prevented, having less deterioration of toughness and having high strength can be manufactured.

摘要： PURPOSE:To obtain the fiber reinforced composite material having excellent strength by pressurizing powder metal as a matrix and mixed slurry of reinforcing short fibers into a billet in which the short fibers are oriented and subjecting the billet to hot extruding in the oriented direction of the short fibers. CONSTITUTION:Powder 10 of an Al alloy as a matrix and SiC whiskers 12 are subjected to wet blending to form slurry 14, which is extruded in the direction of the arrow X at a relatively low extrusion ratio not so as to break the SiC whiskers 12. Next, the material is drained and dried to form into a billet 16. In the reduction stage at the time of forming the billet, the SiC whiskers 12 are oriented in the direction of the arrow X. After a gas in the billet 16 is removed, the billet is heated, is hot-extruded in the direction of the arrow X and is sintered to form a composite material 18. The fiber reinforced composite material having high strength can be obtd. without reducing the aspect ratio in SiC whiskers.
