dc.description.abstractSingle crystals undergoing a strain-induced martensitic transition produce ultrasonic acoustic emission. A CuAlNi elongated sample is bent and unbent at a constant rate to cause the martensitic transformation between a cubic and a monoclinic phase. We have been able to detect and locate the fronts that separate the two phases by using three piezoelectric ultrasonic sensors. Additionally, we have measured the energies of the acoustic emission events and fitted their statistical distribution to a log-normal probability densityca
