“…Unfortunately, the results of similar investigations quoted in [5,6] are not convenient to be compared with our results since the authors of [5,6] did not take into account the essential effect of the above considered error of the estimation procedure. Therefore, we performed our procedure of modeling for the temperature 773 K using the composition of alloys and the values of integral intensities of Mo È ssbauer spectra components P 0 , P 1 , P 90 2 and P 180 2 ) taken from [5,6] for the estimation of energy parameter ranges b 0X075 0X010 AE 0X003 [6] ( Fig.…”

“…In the case of Fe±N austenite the difference between the results of both studies is considerable. The analysis of our estimation results has shown that the position and shape of the region of allowable values of the N±N interaction energies is sensitive to the absolute values of C N , P 0 , P 1 P [5,6]. The notations are the same as in Fig.…”

“…Note, that the separation of contributions from Fe 1 and Fe 90 2 atoms is impossible [9], therefore, the total contribution P 1 P 90 2 can be determined. The thickness dependence of S n aSS n values was found out to be weaker (see, also [10]) than the thickness dependence of the corresponding intensity ratio I n aSI n (I n is the intensity of the n-th spectrum component) obtained in papers [5,14]. Notice, that we used the S n aSS n values for the above-mentioned extrapolation procedure to ªzeroº thickness of the samples as these values, according to [15], include (contradictory to the I n aSI n ratios) the essential nonlinearity in the dependence of the linewidth on the absorber thickness.…”

The energies of interaction between the interstitial atoms within two nearest coordination shells in f.c.c. Fe±9.87 at% N and Fe±7.66 at% C alloys were estimated on the basis of a comparison of Monte Carlo computer simulation results on the short-range atomic order with the corresponding experimental data obtained by means of Mo È ssbauer spectroscopy. Unlike the previous studies here a strain-induced interaction between interstitial atoms within the nearest six interstitial coordination shells (whose energy parameters were independently calculated) was taken into account. The effect of the temperature variation of atomic distribution ªfreezingº at cooling on the values of energy parameters was analysed.x osnovnii srvneni¾ rezul5ttov komp5Ïternogo modelirovni¾ metodom wonte urlo liwnego tomnogo por¾dk s sootvetstvuÏ §imi dnnymiD poluqennymi s pomo §5Ï wessuCrovskoj spektroskopiiD yli oeneny Cnergii vzimodejstvi¾ mewE du tommi vnedreni¾ v rmkh dvuh liwjxih koordinionnyh sfer v qgu Fe±9X87 at% N and Fe±7X66 at% C splvhF otliqie ot pred5du §ih issledovnij v nsE to¾ §ej rote ylo uqteno deformionnoe vzimodejstvie mewdu tommi vnedreni¾ v rmkh xesti liwjxih koordinionnyh sfer @dl¾ kotoryh Cnergetiqeskie prmeE try yli vyqisleny nezvisimoAF fylo pronlizirovno vli¾nie izmeneni¾ temperE tury ªzmorwivni¾º tomnogo rspredeleni¾ pri ohlwdenii n znqeni¾ CnergetiE qeskih prmetrovF

Abstract. Monte Carlo simulations, analytical calculations and thermodynamic activity data have been combined in a study of the distribution of interstitial nitrogen atoms in the octahedral sites of the Pe-N solid solution. Two models are compared in the analysis of the Mossbauer spectra. Thermodynamic activity data are analyzed in terms of the quasichemical approximation to the statistical mechanics of interstitial solutions. The formation energies of the N-N pairs thus assessed are used as input in both Monte Carlo simulations and the quasichemical calculations. A significant discrepancy between Monte Carlo predictions and the Mossbauer results is detected. This striking effect becomes particularly important when the ordered structure model is applied in the analysis of Mossbauer data.
