When chill-metal was used to disk-like casting specimens in low-melting Ni-Cu-Mn alloy, the following results were obtained in comparison with air-vent system: dendritic A-grain changed spherically, and the amount of B-grain increased. In case of grain-size distribution, C-grain changed to a very small-scale, but the others (A- and B-grains) showed the same change as air-vent system. In addition, the segregation distribution of Ni, Cu, Mn, Cr and Ge in individual grains was found, similarly to air-vent system.
当使用冷铁对低熔点镍 - 铜 - 锰合金的盘状铸造试样进行处理时，与通气系统相比，得到了以下结果：树枝状A晶粒变成球形，B晶粒数量增加。在晶粒尺寸分布方面，C晶粒变为非常小的尺寸，但其他晶粒（A晶粒和B晶粒）与通气系统表现出相同的变化。此外，与通气系统类似，发现了Ni、Cu、Mn、Cr和Ge在各个晶粒中的偏析分布。
