摘要
用金相探针法研究了一种低偏析高温合金的凝固。经研究发现，合金中除了钛有轻微的正树枝状偏析外，铬、钴、钼、铝等几乎不发生树枝状偏析；但在共晶内部和前沿。
The metallography microprobe method has been used to study the solidification process and segregation of a low segregated superalloy. It is found that Ti has slight positive branch segregation and Cr, Co, Mo, Al hardly have, but the solidified segregation in and in front of the eutectic is nearly the same as the common superalloy.
