N2 - Two different types of dislocation loops were found in hydrogen ion implanted pure iron after annealing. The natures of these dislocation loops have been characterized by the inside-outside method of transmission electron microscope (TEM). It is found that the dislocation loops in specimens annealed at 670 K are interstitial type with b = 1/2(1 1 1), n ≈ (1 1 2), and the dislocation loops in the specimens annealed at 770 K are vacancy type with b = 1/2(1 1 1), n ≈ (0 1 1) or b = (1 0 0) and, n ≈ (1 1 2). Adding nickle element in iron could decrease the formation temperature of the vacancy loops.
