    摘要： A process of making a composite of a sintered layer on a metal core member, such as an extruder screw having a sintered hard layer on a steel core, by charging a green compact sintering powder material into a space between an inner surface of a compressible mold and an outer surface of a mold core, sealing the compressible mold with the green compact material and the mold core therein, isostatic pressing the sealed compressible mold with the green compact material and the mold core therein, removing the mold core from the isostatically pressed green compact thus forming a cavity therein, inserting a metal core in the cavity in the isostatically pressed green compact with the metal core having a smaller transverse cross-section than the previously removed mold core and shrinking and bonding the isostatically pressed green compact onto the metal core by heating the isostatically pressed green compact and the metal core to a temperature at which the isostatically pressed green compact is sintered resulting in shrinkage thereof and bonding of the sintered material onto the metal core.

    摘要： A purpose of the present invention is to provide material of an aperture grille used for a color picture tube having excellent yield strength, excellent high temperature creep strength and excellent magnetic characteristic, material of an aperture grille used for a color picture tube for improving an occurrence of cracking during a hot rolling step, a method for producing these material, an aperture grille and a color picture tube with the aperture grille. After adding nickel of 0.01 to 1.75 wt % to low carbon alloy steel including copper of 0.05 to 2.5 wt % and phosphor of 0.001 to 0.4 wt %, material according to the present invention is cold rolled. Then, a precipitation treatment is processed at a temperature of 300 to 700° C. Alternatively, the material is cold rolled and secondary rolled after passing through an intermediate annealing at a temperature of 500 to 800° C. Then, the precipitation treatment is processed.
