    摘要： The invention offers a magnesium alloy sheet material having excellent plastic processibility and rigidity and a magnesium alloy formed body having excellent rigidity. The sheet material has magnesium alloy that forms the matrix containing hard particles. The region from the surface of the sheet material to a position away from the surface by 40% of the thickness of the sheet material is defined as the surface region, and the remaining region as the center region. Hard particles existing in the center region have a maximum diameter of more than 20 µm and less than 50 µm, and hard particles existing in the surface region have a maximum diameter of 20 µm or less. Because the hard particles existing at the surface side are fine particles, they are less likely to become the starting point of cracking or another defect at the time of plastic processing. Because the hard particles existing in the center region are coarse, they can increase the rigidity of the sheet material.

    摘要： A process for producing a multi-layered amorphous alloy containing at least one amorphous alloy layer, which involves the step of ejecting a first molten metal onto one of juxtaposed pair of rolls rotating at high speed to thereby cause the molten metal to revolve along the roll surface in a layer state for quenching, the step of ejecting a second molten metal different from said first metal onto the first metal on said roll to quench and form a two-layered metal layer on the rotating roll, and the step of pressure-welding and milling said metal layer between said pair of rolls. This process can be widely utilized for the production of multi-layered alloys for use as various kinds of composite alloy materials such as a highly sensitive bimetal, superconductive wire, a contact spring composite alloy, a latching relay having two-stage magnetic hysteresis, a magnetic head with high performance, etc.
