The stabilisation kinetics of polycrystalline Cu-Zn-Al martensite are studied by means of thermoelectric power measurements (TEP). It is shown that the TEP increases until it reaches a saturation value, which is temperature dependent. The martensite can be further stabilised by increasing the ageing temperature, while subsequent destabilisation by lowering the ageing temperature is not observed. On the basis of these results, a discussion is presented on the important aspects of martensite stabilisation in Cu-Zn-Al.
