查询词典 solidification

The measurement of the flow visualization by shadowgraph technique, movement of liquid-mush interfaces, temperature distribution and concentration distribution were conducted during solidification.

实验主要分为四大部份：暗影法流场可视化、固液界面位置量测、温度分布量测与浓度分布量测。

In this paper, the influence of organic matter content on silt solidification effect was focused on.

研究有机质对淤泥固化效果的影响并针对这种不利影响提出相应的对策是淤泥固化研究中的一个新的课题。

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。

In addition, a self-designed simulant solidification experiment verified this view. The morphology and the size of Si were also studied.

通过自行设计的沉积阶段凝固的模拟实验，对这一机理进行了验证；另外，还对Si相的形态、尺寸进行了一定的研究。

Under such a solidification condition that the growth rate is low and the temperature gradient ahead of the solidi fication front is steep, a large amount of α-Al nuclei can be produced by peritectic reaction, during which only metastable Al〓Zr particles or very fine equilibrium Al〓Zr particles rather than larger equilibrium Al〓Zr partiles are involved.

在低的生长速度和高的界面前沿温度梯度条件下，结晶前沿Al〓Zr粒子与液态铝发生包晶反应（只涉及亚稳Al〓Zr或尺寸极小的平衡Al〓Zr，而不涉及尺寸较大的平衡Al〓Zr）产生大量α晶胚，α晶胚呈球面生长，最终形成等轴非枝晶形态。

This is due to the effect of Zr on solidification behaviour.

这与Zr对合金凝固行为的影响有关。

Therefore, the simulation of solidification will be a very important step in the casting production.

因此，凝固模拟将成为铸造生产过程中一个非常重要的环节。
