Abstract
The kinetics of the formation and of the annealing-out of Fe antistruc ture atoms in the FeAl intermetallic compound of composition Fe52Al48 were investigated by magnetothermal analysis. Data confirm the results previously found for Fe50Al50. The annealing-out depends appreciably on the quenching temperature; the transition from one defect type (tri ple defects) to another (pairs of defects) at approximately 850 degree s C is verified. The migration enthalpies determined from annealing ex periments with different heating rates are slightly higher than for th e stoichiometric composition Fe50Al50.
