Microscopic structure of Fe-Ni and Fe-Ni-S molten alloys of geophysical interest
The static S(Q) liquid structure factors for binary FexNi12x , x50.90, 0.85, and ternary Fe0.85Ni0.05S0.15 molten alloys are investigated by means of the concurrent use of neutron diffraction and reverse Monte Carlo simulations. The measured G(r) radial distributions reveal atomic orderings varying from that present in the Fe0.90Ni0.10 alloy, reminiscent of the ideal bcc structure of solid Fe, ...
متن کاملHydrogen-vacancy interactions in Fe-C alloys.
Energetics and concentrations of hydrogen-containing point defect clusters (PDCs) in Fe-C alloys are calculated and cast into a PDC dominance diagram. Because of the strong binding effects of iron vacancies on the stability of the clusters, hydrogen accumulation requires the total hydrogen and vacancy concentrations to be comparable. As a result of the interplay between repulsive and attractive...

متن کاملMechanical behaviour of Fe-C alloys during phase transformations
The mechanical behaviour of Fe-C aiioys have been determined in their phase transformation ranges during isothermal or anisothermal transformations. Two models an analytical model and a fii te element model have been used in order to calculate the behaviour of the material. Considering a macroscopic scale, these models show that the mechanical behaviour can be well described when an additional ...
متن کاملPoint defect concentrations in metastable Fe-C alloys.
Point defect species and concentrations in metastable Fe-C alloys are determined using density functional theory and a constrained free-energy functional. Carbon interstitials dominate unless iron vacancies are in significant excess, whereas excess carbon causes greatly enhanced vacancy concentration. Our predictions are amenable to experimental verification; they provide a baseline for rationa...
