Absolute concentration of free volume-type defects in ultrafine-grained Fe prepared by high-pressure torsion
A maximum excess volume ΔV/V ≈ 1.9 × 10(−3) in ultrafine-grained Fe prepared by high-pressure torsion is determined by measurements of the irreversible length change upon annealing employing a high-resolution differential dilatometer. Since dislocations and equilibrium-type grain boundaries cannot f...
