Abstract

Measurements of the Acoustic Emission generated during a Martensitic Transformation are presented. Statistical analysis of the amplitude and lifetime of signals has revealed power-law distributions for both magnitudes. The critical exponents of these distributions have been evaluated. The results are discussed in terms of modern theories of avalanche dynamics for first order phase transitions.
