Description
A dose of 2 x 1017 ions/cm2 of nitrogen at 150 keV is implanted into pure polycrystalline nickel. The specimens with and without nitrogen ion implantation are tested in tension-zero fatigue. A 21% increase in endurance limit is found with implantation. The fatigued surfaces are examined by SEM. A lower rate and intensity of slip bands in implanted materials are found. Slip band cracking which is found in the unimplanted specimens is replaced by grain boundary cracking in the implanted specimens. The concentration profile of nitrogen is investigated with AES.
