Vacancy-induced hardening in Fe-Al alloys

Original language description

Hardness of Fe-Al alloys shows a non-trivial dependence on chemical composition and thermal treatment of samples and cannot be fully explained by consideration of intermetallic phases formed according to the equilibrium phase diagram of Fe-Al system. Hardening in Fe- Al alloys caused by quenched-in non-equilibrium vacancies was studied in this work. Non- equilibrium vacancies introduced into the alloys by quenching from 1000 C were detected by means of positron annihilation spectroscopy. The concentration of quenched-in vacancies was found to strongly increase with increasing Al content from 105 at.1 in the alloy with cAl = 18 at. % up to 101 at.1 in the alloy with cAl = 45 at. %. Comparison of the vacancy concentration and the Vickers microhardness revealed that hardening is proportional to square root of concentration of quenched-in vacancies.
