In low-melting 32 Ni-23 Cu-25 Mn alloy, the structure change and the segregation distribution were investigated in optical microscopy. The use of air-vent system to casting specimen had a notable effect to morphology and grain-size distribution, but the segregation showed the same tendency as the air-cooled specimen without air-vent system, except Cu segregated in B-grain less than in C-grain.
在低熔点的32Ni-23Cu-25Mn合金中，利用光学显微镜研究了其结构变化和偏析分布。使用排气系统铸造试样对其形态和晶粒尺寸分布有显著影响，但除了B晶粒中的Cu偏析比C晶粒中的少之外，偏析情况与无排气系统的空冷试样呈现相同趋势。
