ｏｎ以上では靭性が低下して実用上問題が出やすい。The present invention solves this problem, and by dispersing colored ceramics into metal phases of different colors using a dispersion casting method, it is possible to create a new decorative alloy in which particles of different colors are dispersed. Ta. The characteristics of the present invention are to improve the wettability between ceramic and metal, improve the bonding strength at the interface, and prevent the occurrence of cracks due to the difference in expansion coefficient between ceramic particles and metal during solidification. The purpose is to meta-twise the surface. The ceramic grains used in the present invention have an average grain size of 0.2 as the decorative effect.
A size of ~3II+- is required.If it is smaller than this, it will be too thin and the effect cannot be seen with the naked eye, and if it exceeds 0 or 3FJφ, it will be too coarse and will not look good as a decorative part. The above particle size range is optimal. Further, when the ceramic surface is porous with a true density of about 98 inches or less, a particularly excellent bonding effect with the MetaTwis layer can be produced. When the true density is 98% or more, there are few bores on the surface of the sphere, so the bonding force with the MetaTwis layer is weak, and
If it is less than 0%, it is difficult to obtain a surface that can withstand practical use by polishing after sintering, but a very strong bonding force can be obtained. Furthermore, the quality of the metal that metatizes the ceramic varies depending on the combination with the ceramic material, but generally speaking, the optimal thickness is between 0.1 μm and 5 μm. 0
．． If the thickness is less than 1 μm, the MetaTwize layer has a drawback that it is difficult to maintain a bonding effect with the metal layer, and the wettability is poor and cracks are likely to occur during sintering. On the other hand, if the thickness is more than 5 .mu.m, the cost of using the MetaTwize becomes high, and the sintered backward portion is likely to have a bore due to occluded gas in the MetaTwize layer. In this alloy, the appropriate volume ratio of ceramic is 20 to 50 cm.
If it is less than 20%, the effect of ceramic dispersion will not be visible<<, 5
If it is on or above, the toughness decreases and practical problems tend to occur.

をすることが有効である。In the dispersion casting method according to the present invention, it is effective to perform hot isostatic pressing treatment after casting in order to advance the interfacial reaction between the ceramic phase and the metal phase and to eliminate internal bubbles during dispersion. be.
熱間静水圧プレスの条件としては、５００〜１０００気

When we conducted an observation feeding test, no problems such as discoloration occurred. Furthermore, even if a watch body is manufactured using the above alloy, a cover glass, a case back, etc. are assembled, and the watch body falls onto concrete, the result will be 1.5? There were no problems such as cracks up to the height of the pipe, and there were no practical problems. Although this alloy has various characteristics sufficient to be used as a decorative alloy, it was possible to create a new type of decorative alloy in which white ceramic particles are surrounded by a silvery-white metal layer. .

This alloy was polished under the same conditions as in Example 1 and evaluated in the same manner. As a result, no particular problem occurred in corrosion resistance, impact resistance, etc. This alloy has various properties equivalent to the conventional cemented carbide 2, but it also has hp2o3-Tic.
By combining the black ceramic surroundings with a gold alloy, we were able to create a multi-colored alloy with a new color tone. When this alloy was used as part of a pendant, it was possible to use it as a new material with a luxurious feel that was not previously available. Further, by applying the above method to wax using dispersion casting, it is possible to produce multicolored decorative parts.
