Abstract
The implantation with nitrogen ions accelerated at 150 kV has been per formed on sheets of high purity iron (99.99%) annealed for 1.8 ks at 7 73 K and/or cold-rolled with 90% reduction. Dose of the ions was chang ed in the range of 8 x 10(18) to 4 x 10(20) N-2(+)/m(2). Hardness incr eased for a wide range in depth and its increment is large in the defo rmed specimen compared with the annealed and implanted specimen. Iron nitride, Fe16N2 (alpha ''), is formed in both the deformed and the ann ealed specimens, and the size of alpha '' particle in the former is sm aller than that in the latter. The formation of alpha '' in the deform ed specimen is accompanied by the disappearance of dislocation substru ctures.
