与冷坩锅做方法由的一粒新种子关掉技术被建议。有圆柱的结构的熄灭的种子有的冷坩锅冷坩锅的,和罐头直接为方向性的团结被使用的类似的剖面图形状处理。建议方法能显著地简化播种方向性的团结过程并且从用机器制造的种子避免污染。
A new seed making method with cold crucible by power off technique was proposed. The cold crucible quenched seed with columnar structure has a similar cross-section shape as that of the cold crucible, and can be directly used for the directional solidification processes. The proposed method can significantly simplify the seeded directional solidification process and avoid the contamination from the seed machining.
