Abstract
Measurements of the Acoustic Emission generated during a Martensitic T ransformation are presented. Statistical analysis of the amplitude and lifetime of signals has revealed power-law distributions for both mag nitudes. The critical exponents of these distributions have been evalu ated. The results are discussed in terms of modem theories of avalanch e dynamics for first order phase transitions.
