摘要：

Acoustic emission avalanche distributions are studied in different alloy systems that exhibit a phase transition from a bce to a close-packed structure. After a small number of thermal cycles through the transition, the distributions become critically stable (exhibit power-law behavior) and can be characterized by an exponent alpha. The values of alpha can be classified into universality classes, which depend exclusively on the symmetry of the resulting close-packed structure.
