It was indicated by the CALPHAD that the solute content at the end point of primary solidification changes synchronistically with the start point, solute content in dendritic arm and the partition coefficient increase with the solid fraction. Simple Scheil equation was shown to be able to calculate the eutectic amount on the base of partition coefficient calculated by thermodynamics, its prediction for the different solutes is self--consistent and agreeable with the CALPHAD. The eutectic amount and SDAS was measured in DC experiment and compared to model value, it was shown that the experimental data are in agreement with the model prediction.

相图计算耦合Scheil模型的计算结果显示， Al--Cu--Zn合金单相凝固结束点的溶质含量与凝固初始点的成分同步变化，溶质含量和溶质分凝系数随凝固过程的进行不断增加；在热力学计算出合金分凝系数的基础上，简单Scheil方程可以计算初生相含量，从不同溶质得到的计算结果是自洽的，并与相图计算耦合Scheil模型的预测值一致；实验测定了不同成分铝合金的共晶含量和枝晶间距，实验数据与模型结果基本一致。

It is found that the increase in the diameter of oxide which grows during solidification is larger when the size of oxide before solidification and cooling rate during solidi...

此外，可以根据冷却速率和凝固后氧化物的直径判断氧化物是凝固前形成的一次氧化物还是凝固过程中产生的二次氧化物。

The melting zone in explosive consolidating HSS sample has heen investigated by TEM and SEM, and founds the solidifying structure of the liquid phase is consisted by δ-ferrite and carbide that are uniformity and disper. It shows the solidifying rate of the liquid phase is very rapid. and is higher than the cooling rate of the casting and atomization of nitrogen.

对高速钢爆炸固结样品中熔化区用扫描电镜、透射电镜研究发现：爆炸固结过程中形成液相的凝固组织为极其细小均匀的等轴δ-铁素体晶粒和碳化物，表明液相的凝固速度非常快，远远大于铸锭凝固的冷却速度和氮气雾化制粉的冷却速度。

Precursor used in this experiment was spun in coagulating bath in different temperature, while the concentration in the bath maintained 60%.

In the medium scale experiment line, the best concentration of coagulation was about72% It was showed that the increasing of the concentration of was good for decreasing surface puckers and made the cross-section shapes tend to circle.

在中试线上，最佳凝固浴浓度为72%左右。对凝固浴浓度与纤维表面形态的研究表明：凝固浴浓度的升高有利于降低纤维表面沟槽，截面更趋于圆形。

By the OM and SEM observation of solidification microstructure, the interfacial reaction between TiAl alloy and Al2O3 crucible was serious, and a large number of α-Al2O3 inclusion formed in the solidification microstructure. The interfacial reaction between TiAl alloy and ZrO2 crucible occurred only on the sample surface, but the crucible was not stable at high temperature and a tack coating was formed, clinging tightly with TiAl alloy. C element in the graphite crucible changed the original solidification path of TiAl alloy, and club-shaped γ-TiAl phases formed.

通过用光学显微镜和扫描电镜对凝固组织观察发现，TiAl合金与氧化铝坩埚之间的界面反应较为严重，在凝固组织中形成了大量氧化铝夹杂；TiAl合金与氧化锆坩埚的界面反应仅发生在试样表面，但该坩埚在高温下不稳定，并在试棒表面形成一层无法剥离的粘结层；石墨坩埚中的C元素改变了原有TiAl合金的凝固路径，生成了棒状的γ-TiAl相。

In order to obtain better directional solidification microstructure, the whole directional solidification technique needing crucibles

为了获得更好的定向凝固组织，需要在超高温超高真空定向凝固设备上进行有坩埚的整体定向凝固。

Solidification simulation was used for gatings of three different structures with the help of Magma soft Based on the simulation results of appearance defects and inner shrinkage porosity of the castings, the different technology improvements were brought forward.
