Popis:	The positron lifetime measurement to investigate phase transformations: martensitic phase (MP) parent phase (PP) in CuZnAl alloy has been used. We have observed the generation of new defects by MP PP transformation; these defects are liquidated by martensitic transformation. This effect is only observed in case of high concentration vacancies in alloy. In order to explain the nature of these defects we take into consideration the supervacancies idea.
