The high concentration of vacancies induced by β″ phase formation in Al–Mg–Si alloys has been observed by positron annihilation lifetime spectroscopy. These vacancies differ from quenched-in vacanc...

The strain-rate dependence of vacancy cluster sizes in hydrogen-charged martensitic steel AISI410 under tensile deformation was investigated using positron lifetime spectroscopy. The vacancy-cluster sizes in hydrogen-charged samples tended to increas

We investigate the energetics and structures of martensitic phases in NiTi and the effects of chemical composition using first-principles calculations. We calculate the accurate energy landscape for the transformation from the B19 to BCO phases, whic
