5.The low cycle fatigue properties of polycrystalline α-Fe before and after the implantation of Ag￣+ ions by 90 keV and 6×10￣(16) ions/cm2 arestudied in this paper. Results thew that adn implantation improves the low cycle fatigue properties of α-Fe. The fatigue toughness factor and fatigue tongness index are increased from 0. 076 and 0. 32 before iniplantation to 0. 216and 0.42 respectively after implantation.
