Sažetak
The double martensitic transformation in the p 1 Cu-Zn alloy was studied using dilatation measurement and acoustic emission (AE) analysis represented by root mean square (rms) voltage and ring-down counting. The slowly growing banded martensite is distinguished by dilatometric changes and very low amplitude, high repetition rate acoustic emission. The burst type martensite is completely self-accommodated, accompanied by high amplitude, low repetition rate emission bursts. The effect of thermal cycling on both the number of ring-down counts and the apparent martensitic start and end temperatures is discussed.
