A polyester film for metal sheet laminating. The film comprises a blend of (I) polybutylene terephthalate or a polyester comprising it as the main ingredient with (II) polyethylene terephthalte or a polyester comprising it as the main ingredient, the contents of the polyester (I) and the polyester (II) being 80 to 40 wt % and 20 to 60 wt %, respectively. This film has a melting point of 200 to 223&deg; C. attributable to the polyester (I) and a melting point of 230 to 256&deg; C. attributable to the polyester (II). The film as a whole has an intrinsic viscosity of 0.75 or higher.

Polyester film for metal sheet laminating, metal sheet laminated with this film, and metal vessel formed from this metal sheet

A polyester film made of a mixture comprising a thermoplastic polyester (A) as a matrix component and a thermoplastic polyamide (B) having a glass transition temperature higher than the thermoplastic polyester (A), as a dispersed component, or a laminated film having a surface layer made of said mixture, wherein the film surface has fine protuberances formed with said thermoplastic polyamide (B) as nuclei.

An electrically conductive composite material is formed by dispersing in a matrix metal the other metal which is not solid soluble with the matrix metal. The other metal is finely divided to an extent of not excessively lowering the conductivity and is mixed in the matrix metal in a particle amount with which respective particles keep a mutual distance effective to strengthen the composite material, whereby the material is sufficiently improved in the mechanical strength and wear resistance and remarkably reduced in the high temperature deformation. Such conductive composite material can be obtained through a melt atomization.

An electrically conductive composite material is formed by dispersing in a matrix metal another metal which is insoluble or slightly soluble with the matrix metal. The other metal is finely divided to an extent of not excessively lowering the conductivity and is mixed in the matrix metal in a particle amount such that respective particles keep a mutual distance effective to strengthen the composite material. The material is thereby sufficiently improved in the mechanical strength and wear resistance and remarkably reduced in high temperature deformation. Such conductive composite material can be obtained through a melt atomization.

An iron-base amorphous alloy is described, having improved fatigue and toughness characteristics consisting essentially of from 6 to 16 atom % Si, from 7.5 to 16 atom % B, and from 2 to 9 atom % Cr, provided that the composition ranges of Si, B, and Cr are within the quadrangles defined by a-b-c-d of FIG. 1, and e.sub.1 -f.sub.1 -g.sub.1 -h.sub.1 of FIG. 2, and the balance being substantially Fe. In addition to improved fatigue and toughness characteristics, the amorphous alloy has excellent tensile break strength, heat resistance, corrosion resistance and electromagnetic properties, and is therefore very useful for industrial reinforcements and electromagnetic materials.
