定向凝固　　在熔模铸造型壳中建立特定方向的温度梯度，使熔融合金沿着与热流相反的方向按照要求的结晶取向凝固的一种铸造工艺。定向凝固技术最突出的成就是在航空工业中的应用。自1965年美国普拉特·惠特尼航空公司采用高温合金定向凝固技术以来，这项技术已经在许多国家得到应用。采用定向凝固技术可以生产具有优良的抗热冲击性能、较长的疲劳寿命、较好的蠕变抗力和中温塑性的薄壁空心涡轮叶片。应用这种技术能使涡轮叶片的使用温度提高10～30°C，涡轮进口温度提高20～60°C，从而提高发动机的推力和可靠性，并延长使用寿命。　　　　普通铸件一般均由无一定结晶方向的多晶体组成。在高温疲劳和?浔涔讨校怪庇谥饔αΦ暮嵯蚓Ы缤橇盐撇屠┱沟闹饕课唬彩俏新忠镀呶鹿ぷ魇钡谋∪趸方凇２捎枚ㄏ蚰碳际蹩苫竦蒙し较蛴胫饔αΨ较蛞恢碌牡ハ蛏さ闹淳澹ḿ迹６ㄏ蚰逃捎谙撕嵯蚓Ы纾佣岣吡瞬牧峡垢呶氯浔浜推＠偷哪芰Α６ㄏ蚰讨淖橹治础⒌ゾШ投ㄏ蚬簿?3种。　　　　　　铸件定向凝固需要两个条件：首先，热流向单一方向流动并垂直于生长中的固-液界面；其次,晶体生长前方的熔液中没有稳定的结晶核心。为此，在工艺上必须采取措施避免侧向散热,同时在靠近固-液界面的熔液中应造成较大的温度梯度。这是保证定向柱晶和单晶生长挺直，取向正确的基本要素。以提高合金中的温度梯度为出发点，定向凝固技术已由功率降低法、快速凝固法发展到液态金属冷却法。
