Abstract
The significance of thermal fluctuations in nucleation in structural first- order phase transitions has been examined. The prototypical case of martens itic transitions has been experimentally investigated by means of acoustic emission techniques. We propose a model based on the mean first-passage tim e to account for the experimental observations. Our study provides a unifie d framework to establish the conditions for isothermal and athermal transit ions to be observed.
