Process for producing multi-layered alloys.

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 roll onto rotating at high speed to thereby cause the molten metal to revolve along the roll surface in a layer state for quenching, and 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. 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 wires, a contact spring composite alloy, a latching relay having two-stage magnetic hysteresis, a magnetic head with high performance, etc.
