通常报告的意见有关的任何建议的解释的柱状等轴转变（CET）作为凝固合金最初被认为是。审查，然后继续考虑拟议的机制等轴晶的形成，合金和加工条件对CET的影响，柱状生长的终止标准，最后，确定性/随机模型预测CET。最后，对CET和当前建模能力的理解水平进行了总结和评估。
The generally reported observations pertinent to any proposed interpretation of the columnar to equiaxed transition (CET) in as solidified alloys are initially considered. The review then proceeds to consider the proposed mechanisms of equiaxed grain formation, the influence of alloy and processing conditions on the CET, criteria for the termination of columnar growth and, finally, deterministic/stochastic models for predicting the CET. In conclusion, the present level of understanding of the CET and current modelling capabilities are summarised and assessed.
