为了研究等轴晶形核过冷度对NPG-DC合金系柱状晶向等轴晶转变的影响，我们进行了相场模拟。我们的相场模型是基于多相场方法。的模拟参数进行了调整，以微重力实验纯扩散生长条件下进行。在TEXUS-47探空火箭活动期间进行了实验研究。
We have performed phase field simulations in order to explore the effect of equiaxed grain nucleation undercooling on the columnar to equiaxed transition "CET" in the NPG-DC alloy system. Our phase field model is based on the multiphase-field method. The simulation parameters are adapted to a microgravity experiment performed under purely diffusive growth conditions. The experimental investigation is made during the sounding rocket campaign TEXUS-47.
