Abstract
The phase transition of the CsCl ⇌ NaCl type structure was followed in CsCl, NH 4Cl and NH 4Br powder samples by simultaneous AE-DTA measurement. Acoustic emission (AE) was detected during the transition, which arose from cracking and/or the transition itself. The cumulative counts of AE during the forward and backward transitions decreased with the number of repeated heating/cooling cycles, and finally became constant. The averaged power spectra of AE in three samples were found to be similar to each other and consist of low (50–400 kHz) and high frequency (above 500 kHz) components. The latter tended to decrease with a repeated number of the cycles.
