摘要

实验表明，水和铋在玻璃和石英圆柱形中的定向凝固不会导致铸件垂直于凝固方向的膨胀。因此，这些形式不会被破坏。这是由于水和铋定向凝固过程中气体的畅通无阻的释放。气体对铸件凝固时的膨胀过程有很大的影响。

Influence of gases on casting expansion processes during their hardening

It has been experimentally shown that directional solidification of water and bismuth in glass and quartz cylindrical forms does not result in expansion of the castings perpendicular to the solidification direction. Therefore, such forms are not destroyed. This is due to the unobstructed release of gases during directional solidification of water and bismuth. Gases have a great influence on the expansion processes of castings when they solidify.
