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.

摘要： PROBLEM TO BE SOLVED: To provide a clutch which has a durability to bear a high load and a high temperature, by making a carbon crystal sedimentary layer at a specific thickness, and the strength ratio at a specific value of peak of the Raman spectrum within a specific scope. SOLUTION: The thickness of a carbon crystal sedimentary layer Lc indicates the lamination of a carbon layer in the layer structure in a C/C composite, and the Lc is made 2 to 70nm, favorably 10 to 40nm. On the other hand, by the Raman spectrum, the existing ratio of the carbon forming a layer structure, and the carbon forming no layer structure in the C/C composite, can be known. As a result, a Raman band near 1,360cm indicates the existence of an amorphous form carbon, while the Raman band near 1,600cm indicates the existence of a graphite crystal structure. The strength ratio of the peak of the Raman spectrum near 1,360cm , and the peak near 1.600cm , is specified as 0.4 to 0.9.
