Nitriding of binary and ternary iron-based alloys 7.4 Microstructural development of the diffusion zone in the presence of alloying elements With respect to the development of the diffusion zone a distinction between nitriding and nitrocarburizing need not be made: carbon, as compared to nitrogen, doe...
The purpose of the present communication is to re-examine the data for N-diffusion in bcc iron in the light of Weller's contentions. 展开 关键词: Experimental/ diffusion in solids iron/ Curie temperature C N Fe/ A6630J Diffusion, migration, and displacement of impurities in solids/ Fe/el...

Especially in non-FCC alloys, significant deviations from the anticipated behaviour are observed [27], as it was recently reported for BCC refractory HfTiZrNbTa and HfTiZrNbV alloys [28] and for the HCP AlHfTiScZr HEA system where an ’anti-sluggish’ behaviour was indeed observed [22]. ...
short-circuits of diffusion and trapping processes within grain boundaries in fcc metals and alloys remain a complex subject that is still poorly understood. Furthermore, the confrontation of experience and numerical works has not been currently used in this subject which reduces the quality of the ...
In the present paper, we focus on that part of the activation process played by vacancy migration. We perform computer simulations of the migration of a single vacancy in BCC iron across the phase boundary using spin-lattice dynamics (SLD) [1], allowing active participations of the interacting...
In this study, we performed molecular dynamics (MD) simulations to elucidate the relationship between various stress conditions and the diffusion coefficients of interstitial hydrogen in body-centered-cubic (bcc) iron. The results reveal that the diffusion coefficients are independent of isotropic stress...
However, some reported assessments exist; Jo¨nsson[3] performed assessments for the diffusion of several elements in both the fcc and the bcc phases with focus on iron based systems, Bratberg et al.[4] revised the kinetic description of Cr and V diffusion in the fcc phase and Lindwall ...
A ferritic base centred cubic (bcc) structure enables a high diffusion rate and a low solubility due to its open lattice structure. In contrast, the austenitic face centred cubic (fcc) structure gives a lower diffusion rate and a higher solubility due to its close packed lattice. Martensite ...
