摘要：

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 < 111 >, n approximate to < 112 >, and the dislocation loops in the specimens annealed at 770 K are vacancy type with b =1/2 < 111 >, n approximate to < 011 > or b = < 100 > and, n approximate to < 112 >. Adding nickle element in iron could decrease the formation temperature of the vacancy loops. (C) 2014 Elsevier B.V. All rights reserved.
