Investigation of Defects and Atomic Ordering in Fe72Al28 by Positron Annihilation and Mössbauer Spectroscopy

Abstract

Iron aluminide FeT2Alz8 was investigated in states with different defect concentrations using the positron annihilation lifetime and Mossbauer spectroscopy methods. The dominant component of 178-187 ps, obtained from positron lifetime spectra analysis, corresponds to a high density of vacancies. In the sample where high concentrations of vacancies or… (More)
