Reaction between MnO-SiO2-FeO Inclusion and Steel Matrix Deoxidized by Si and Mn at Different Heat Treatment Temperatures
In order to clarify the effect of heat-treatment temperature on the reaction between solid steel and inclusions, in this study, the reaction between Fe-Mn-Si alloy and MnO-SiO2-FeO oxide during heat-treatment at 1373 K, 1473 K and 1573 K were investigated using diffusion couple method, respectively. The results indicate that the width of the particle-precipitated zone (PPZ) and the Mndepleted z...
متن کاملDensity Functional Study of FeO 2 , FeO + 2 , and FeO − 2 ALFONSO T . GARCÍA - SOSA , MIGUEL CASTRO
The lowest energy structures of FeO2 were determined by means of density functional theory techniques as implemented in the program DGauss 3.0.1. The calculations performed were of the all-electron type using two levels of theory, namely the local spin density approximation with the use of the Vosko–Wilk–Nusair (VWN) functional and the generalized gradient approximation (GGA) in the form of the...
متن کاملPossible polytypism in FeO at high pressures
Examination of X-ray diffraction intensities for FeO collected in situ at high pressure and high temperature reveals that the atomic arrangements of FeO in the hexagonal structure are not the same as those in the simple NiAs-type structure (B8) where Fe takes the place of Ni. The observed diffraction intensity can be explained by adding an anti-B8 component (where Fe takes the place of As). Sub...
متن کاملVibrationally resolved photofragment spectroscopy of FeO
We report the first vibrationally resolved spectroscopic study of FeO. We observe the 0←0 and 1←0 bands of a S←X S transition at 28 648.7 and 29 311 cm. Under slightly modified source conditions the 1←1 transition is observed at 28 473 cm. In addition to establishing an upper limit D0 (Fe1–O!<342.7 kJ/mol, our results give the first experimental measurements of the vibrational frequencies in bo...
متن کاملEquations of state of FeO and CaO
New shock-wave (Hugoniot) and release-adiabatic data for Feo.940 and CaO, to 230 and 175 GPa (2.3 and 1.75 Mbar) respectively, show that both oxides transform from their initial B1 (NaC1-type) structures at about 70 (* 10) GPa. CaO transforms to the B2 (CsC1-type) structure and FeO is inferred to do the same. Alternatively, FeO may undergo an electronic transition, but it probably does not disp...
