摘要
给出了具有包晶反应的合金在定向凝固条件下的成分过冷判据式。作者用计算机将液-固界面前沿的温度实测值进行处理得到温度梯度G,经Sb-Sa合金定向凝固试验证明了判据式的正确性。
The constitutional supercooling criterion of alloys with peritectic reaction in the directional solidification was proposed. The temperature gradient G was obtained by computer to treat the temperature date in front of the liquid-solid interface. The criterion was proved to be correct by the directional solidification experiment on Sb-Sn alloys
