研究了结构一级相变中成核热波动的意义。用声发射技术对马氏体相变的典型情况进行了实验研究。我们提出了一个基于平均首次通过时间的模型来解释实验观察。我们的研究提供了一个统一的框架来建立观察等温和非热转变的条件。
The significance of thermal fluctuations in nucleation in structural first-order phase transitions has been examined. The prototypical case of martensitic transitions has been experimentally investigated by means of acoustic emission techniques. We propose a model based on the mean first-passage time to account for the experimental observations. Our study provides a unified framework to establish the conditions for isothermal and athermal transitions to be observed.
