Abstract
Simultaneous enthalpy and acoustic emission measurements were used to study the β→2H martensitic transformation in a Cu-Zn-Al alloy. The results are compared with those obtained for the β→18R transformation in a Cu-Zn-Al alloy with different composition. The prominent results can be sumarised as follows : the transformation has a jerky growth character and signals obtained are not reproducible from one thermal cycle to the other. The thermoelastic character of this transformation is questionable.
