摘要

用光学显微镜研究了低熔点32 Ni-23 Cu-25 Mn合金的组织变化和偏析分布。排气系统对铸态试样的形貌和晶粒分布有显著影响，但偏析的趋势与未排气系统的铸态试样相同，只是b晶中的Cu偏析量小于c晶。

Microstructure change and segregation distribution in dental 32 Ni-23 Cu-25 Mn casting alloy. (Part 1) Effect of air-vent system.

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.
