摘要： A process for producing fiber-reinforced magnesium alloy materials with improved mechanical properties which includes the steps of placing a shaped article of silicon carbide whiskers or silica type, alumina type or silica-alumina type fibers in a casting mold, and pouring into the mold a molten matrix of a magnesium alloy at a temperature lower than 800.degree. C. The shaped article is impregnated with the molten matrix by means of a high pressure coagulation casting method while maintaining the original configuration of the shaped article to form a composite. A magnesium-silicon compound and/or a magnesium-aluminum compound are precipitated in the matrix at the filling and composite-forming step by reaction between the surface fibers of the shaped article and the molten matrix. The whiskers or fibers may be covered by a film of copper, nickel or silver to vary the amount of the precipitated compounds.

摘要： A method of producing a unidirectional fiber-reinforced composite material by covering bundles of an inorganic fiber having unidirectionally high elasticity and high strength with a wire-like, foil-like or knit-like material which is the same as, or different from, a matrix metal and is capable of being molten and diffused into said matrix metal, to thereby form a fiber body having an optional shape, volume and fiber density; placing the resulting fiber body in an appropriate location within a mold; pouring a molten matrix metal into said mold; and squeeze casting said molten matrix metal along with the fiber body to form the unidirectionally fiber-reinforced composite material while causing said covering material to melt and diffuse under heat of said molten matrix metal into the latter.
