“…Through the annals of literature related to nitriding studies which involve ion implantation, deviation from predicted Gaussian profiles in the form of movement of the profiles towards the surface was clearly observed. Though a majority did not provide any discussion on this aspect, a few have invoked computer codes to account for sputtering and have obtained good fit to the experimental depth profiles [3][4][5][6][7][8][9]. But in the present case, owing to low fluence implantation, the role of sputtering (sputtering yield %1.3 atom/ion) in causing a deviation to the nitrogen profile should be ignored.…”

Auger electron spectroscopy (AES) combined with a well controlled ion mill is applied for the study of nitrogen implanted (N$ ions, 120 keV) into iron single crystals in doses ranging from 8 x 10" to 5 x 1017N-atoms/cm2, also with subsequent heat treatment. The nitrogen depth profiles are Gaussian-like in shape for doses up to 1.5 x 1017 Natoms/cm2. At higher doses deviations are observed.The nitride bonding state was indicated but a part of the implanted nitrogen appears to be weakly bonded.Spektroskopie der Augerelektronen in der Kombination mit einer gut kontrollierten Ioneniitzung wurde zum Studium der Stickstoffimplantation (NS Ionen, 120 keV) in die Eisenmonokristalle ausgenutzt. Die Dosis war 8 . 10ls bis 5 . 10'' N-Atome/cm2. Nachtraglich wurden die Proben auch warmebehandelt. Die Stickstoff-Tiefenprofile haben die GauSsche Form bis zur Dosis 1.5. 1017 N-Atome/cmZ. Bei hoheren Dosen wurden Abweichungen beobachtet. Der Nitridbindungszustand wurde indiziert. Ein Teil des Stickstoffs scheint schwacher gebunden zu sein.

Solution annealed samples of the MnCr austenitic steel Nitronic 32 are uniformly implanted at 310 K with 500 atppm He corresponding to a dose of ≈︁ 0.1 dpa. Specimens are subsequently aged, one set at 773 K and another set at 1023 K; the evolution of the dislocation structure and the related segregation and precipitation phenomena are examined by TEM, EELS, and electron diffraction. Short annealing (2 h) at 1023 K lead to the formation of Frank interstitial dislocation loops which are found enriched in N and Cr. After longer annealing (25 h) at 1023 K, Cr2N precipitated on the loops, small He bubbles becomes visible in the matrix, whereas no lamellar precipitation is observed in contrast to unirradiated specimens.
