Amorphous alloys made of semi-metal elements such as Si, B, P and C have excellent mechanical properties, magnetic properties, corrosion resistance and the like, and are expected to be applied in various ways. These amorphous alloys are currently used in single roll, twin roll, rotating submerged spinning,
It is manufactured by the high pressure gas atomization method or the like. However, the amorphous alloy produced by the above manufacturing method is
Generally, the shape is limited to ribbon, fine wire, powder, etc.,
Further, the cross section is a simple rectangle or circle, and it is difficult to produce an amorphous alloy having a complicated cross section such as a U-shape or an H shape. Further, in order to obtain products of various shapes, it is necessary to further perform processing steps such as compression processing and punching, and in order to maintain excellent characteristics peculiar to amorphous alloys, complicated temperature control during processing is required. Production process control was necessary. Further, since the final product yield is poor in the punching process, the amorphous alloy having a complicated shape is very expensive. On the other hand, Mg group or L having a large amorphous forming ability
It has been reported that a bulk material of a-base amorphous alloy can be obtained by a die casting method [Spring Meeting of the Japan Institute of Metals (1st

は２.０ｋｇ／ｃｍ2以上であることが望ましい。When producing an amorphous alloy according to the present invention,
It is necessary to apply pressure to the molten metal and inject it into the mold, but by applying pressure, the highly viscous melt that forms the amorphous alloy is accurately sent to the mold to prevent shrinkage cavities. , It reduces the heat resistance at the molten metal-mold interface and promotes heat transfer. It is desirable that the pressure applied to the molten metal is 0.5 kg / cm 2 or more, preferably 1.0 kg / cm 2 or more, and more preferably 2.0 kg / cm 2 or more.

を用いれば、所望の圧力を加えた溶湯流を得ることがで
きる。As a method for applying pressure to the molten metal, various known methods can be used, but a method of transmitting the pressure to the molten metal using a gas medium is preferable. For example, the molten metal is held in a ceramics container equipped with a nozzle having a slit shape or a hole having a circular cross section at its lower end, and Ar is placed on the upper surface of the molten metal.
By using a method of pressurizing with an inert gas such as, for example, casting into a mold, a molten metal flow under a desired pressure can be obtained.

合金が製造できなくなる傾向にある。The supply rate of the molten metal to the mold is preferably controlled in the range of 0.1 g / sec or more and 60 g / sec or less by selecting the pressure applied to the molten metal and the nozzle shape. If the feed rate is less than 0.1 g / sec, the flow of molten metal in the mold becomes poor, and defective castings are likely to be formed. When the supply rate is higher than 60 g / sec, the amount of molten metal supplied becomes too large, and a sufficient cooling rate cannot be obtained even if a mold with good heat transfer is used, and an iron group-based amorphous alloy is produced. It tends to be impossible.

Beryllium copper, carbon steel, alloy steel and the like can be mentioned, but copper having a high thermal conductivity is particularly preferable. The shape of the mold is not particularly limited, and various shapes can be used.
Regarding the space (gap) in the mold, the space dimension from metal surface to metal surface is a linear distance of 0.05 mm or more,
It is preferably 30 mm or less. If this space dimension is smaller than 0.05 mm, an imperfect casting is likely to be formed even if pressure is applied to the molten metal for casting. If the space dimension is larger than 0.3 mm, the cooling rate is slow and an iron group-based amorphous alloy cannot be obtained. That is, the method of the present invention is
It is suitable for producing cast products having a wall thickness of 0.05 to 0.30 mm.

It is also possible to manufacture a product having a complicated cross-sectional shape that cannot be manufactured by the single roll method or the like. In the method of the present invention,
Mold casting is preferably performed in an atmosphere of vacuum or an inert gas.

Examples 1 to 4 and Comparative Example 1 A master alloy having the composition shown in Table 1 was melted by high-frequency heating in a quartz nozzle having a nozzle hole of 0.18 mmφ, and then the nozzle was lowered to lower the nozzle into a mold. It is pressed against the top and the molten metal is poured into a mold made of pure copper at various pressures shown in Table 1, and it has a U-shaped cross section and a wall thickness of 0.2 m.
A sample of an amorphous alloy having a length of m and a length of 30 mm was obtained. Table 1 shows the presence or absence of casting defects and the results of structural analysis of the samples. As is clear from Table 1, in Examples 1 to 4, good amorphous alloys having no casting defects were obtained. On the other hand, in Comparative Example 1, since the pressure applied to the molten metal was as low as 0.45 kg / cm 2 , the molten metal supply rate was also 0.05 g / sec, which was slower than that of the example, and shrinkage cavities occurred at several places in the sample. .. Further, since there was a portion where a sufficient cooling rate was not obtained, it had a structure in which crystalline and amorphous were mixed.
