horn spacing

The dendritic arm spacings and microsegregations of directionally solidified superalloy DZ22 at various solidification rates have been studied with the help of a ZMLMC directional solidification equipment.

采用新研制的超高梯度定向凝固装置，研究了不同凝固速率下定向凝固高温合金ＤＺ２２的枝晶臂间距和枝晶偏析。

Research on secondary arm spacing has important significance for improving the mechanical properties of castings.

研究枝晶二次臂间距对于提高铸件力学性能有重要意义。
