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...
متن کاملNucleation mechanism of nano-sized NaZn13-type and α-(Fe,Si) phases in La-Fe-Si alloys during rapid solidification
The nucleation mechanism involving rapid solidification of undercooled La-Fe-Si melts has been studied experimentally and theoretically. The classical nucleation theory-based simulations show a competitive nucleation process between the α-(Fe,Si) phase (size approximately 10 to 30 nm) and the cubic NaZn13-type phase (hereinafter 1:13 phase, size approximately 200 to 400 nm) during rapid solidif...
متن کاملPhase Diagrams of Fe-Si Alloys under High Pressures
Introduction Iron is the most abundant element in the Earth’s core. However, the density of the outer core is about 10% lower than the density of iron at the pressure and temperature conditions of the outer core, indicating the presence of a low-atomic-weight component (such as H, C, O, Si, or S) in the core [1]. There is also evidence that the inner core may be less dense than pure iron and th...
متن کاملRevealing heterogeneous nucleation of primary Si and eutectic Si by AlP in hypereutectic Al-Si alloys.
The heterogeneous nucleation of primary Si and eutectic Si can be attributed to the presence of AlP. Although P, in the form of AlP particles, is usually observed in the centre of primary Si, there is still a lack of detailed investigations on the distribution of P within primary Si and eutectic Si in hypereutectic Al-Si alloys at the atomic scale. Here, we report an atomic-scale experimental i...
متن کاملCyclic Martensitic Transformations Influence on the Diffusion Of Carbon Atoms in Fe-18 wt.%Mn-2 wt.%Si alloy
A significant carbon diffusion mobility acceleration as a result of cyclic γ↔ε martensitic transformations in iron-manganese alloy is determined by one- and two-dimensional structure defects of ε-martensite with face-centered close-packed lattice. Such defects (dislocations, low angle sub-boundaries of dislocations, chaotic stacking faults) were formed during cyclic γ↔ε martensitic transformati...
