The influence of thermal and mechanical treatment on formation and evolution of vacancies in some binary iron-based alloys (Fe-W, Fe-Ti, Fe-V, Fe-Mn, Fe-Ru, Fe-Si) were studied using the transmission Mossbauer spectroscopy (TMS). The obtained results reveal that in the case of Fe-W, Fe-Ti and Fe-V alloys, the vacancies which were generated during arc-melting and cold-rolling processes are located mainly in the vicinity of noniron atoms. This speaks in favour of the suggestion that in the iron matrix the mentioned above solute atoms and vacancies interact attractively which supports the known from the literature theoretical calculations on the vacancy-solute interaction in alpha-Fe. On the other hand, in the case of Fe-Mn, Fe-Ru and Fe-Si alloys the TMS results exclude the presence of vacancy-solute pairs at room temperature.
