Amorphous alloys are often manufactured by a single roll method that easily achieves a high cooling rate. To date, many amorphous alloys have been used for Fe-based, Ni-based, Co-based, Al-based, or Mg-based alloys. Quality alloy material has been obtained.

Application to various fields as an alloy material is expected. Among them, in the case of an alloy system in which a rare earth metal is added to Mg, a Mg-based amorphous alloy having high strength as disclosed in Japanese Patent No. 2705996 and Japanese Patent Application Laid-Open No. 6-41761 has been developed, Application to wood is expected.

The shape of the g-based amorphous alloy is limited to a ribbon, and the application range is limited if the ribbon shape remains unchanged. Therefore, it is required to develop a rod-shaped or other bulk material. In addition, it is not easy to apply a solidification technique to a ribbon-shaped amorphous alloy to process it into an amorphous bulk material.
Amorphous alloys are required.

能に優れたＭｇ系非晶質合金の開発が望まれていた。Generally, an amorphous alloy capable of producing a target shape as it is is produced by a die casting method or a forging using a mold having the target shape. However, when the die casting method is used, the cooling rate is lower than that of the above-described single roll method, and the thickness is reduced to 30 μm by the single roll method.
Even if a bulk material is prototyped using a mold casting method using an alloy composition that can produce an Mg-based amorphous alloy of about m, the bulk material of the amorphous single-phase Mg-based amorphous alloy can be obtained. There was a problem that it could not be obtained. In addition, when forging is used, an amorphous metal larger than a target shape is required, and there is a problem that processing cannot be performed unless a larger bulk material is obtained. Therefore, there has been a demand for the development of a Mg-based amorphous alloy having an excellent amorphous forming ability, whereby an amorphous alloy can be easily obtained even in the case of a mold casting method having a slow cooling rate.
