本文简要介绍初等灾变理论的基本概念和类型,并把尖点灾变模型应用到共析碳钢固态相变的宏观特性研究中。分析结果表明,所用模型较好地反映了金属固态相变的特点,为金属相变宏观特性的分析提供了一种新方法。
This paper briefly introduces the basic concepts and types of elementary catastrophe theory, and applies the cusp catastrophe model to the macroscopic properties of solid state transformation of eutectoid carbon steel. The analysis results show that the model used can well reflect the characteristics of metal solid phase transformation and provide a new method for the analysis of macro-characteristics of metal phase transition.
