Ab initio calculation of the solution enthalpies of substitutional and interstitial impurities in paramagnetic fcc Fe

Magnetic properties of Al, V, Mn, and Ru impurities in Fe–Co alloys

transformation in metastable Fe - Mn alloys

Metastable Fe-Mn alloys exhibit a non-thermoelastic martensitic transformation which is accompanied by a significant thermal effect (ca. 20 J/g). Among Fe-Mn alloys, the highest value of latent heat was registered in alloys with 17-18 wt. % Mn. In this work we investigate effects of carbon (up to 0.4 wt. %) and cold rolling (5-25% of thickness reduction) on the latent heat and the temperature h...

ATOMIC AND MAGNETIC SRO IN Fe-Mn-Si ALLOYS

Neutron diffuse scattering and saturation magnetization experiments have been made on single crystals specimens of Fe3-,MnCSi with c = 0.164 and 0.284 at room temperature. Atomic clustering of Mn atoms on the B sublattice has been revealed. A model of magnetic moment distribution around Mn impurities has been developed and fitted to the experimental magnetic diffuse cross sections. RRsults obta...

Carbon Interstitial Diffusion in γ-Fe

In this paper, we employ a four-frequency model for carbon diffusion in austenite where interstitials can diffuse either as isolated species or pairs. We make use of the Okamura and Allnatt formalism that has recently been shown to be near exact. The general finding of a previous analysis of McKee is confirmed: the increase of both tracer and chemical carbon diffusion coefficients with carbon c...
