Compositional variation of the phonon dispersion curves of bcc Fe-Ga alloys
Inelastic neutron scattering techniques have been used to measure the phonon dispersion curves of bcc Fe1−xGax (x=10.8, 13.3, 16.0, 22.5) alloys as a function of Ga concentration. The phonon frequencies of every branch were found to decrease significantly with increasing Ga concentration. The softening was most pronounced for the T2[ξξ0] branch and, to a lesser extent, the L[ξξξ] branch in the ...
متن کاملPhonon softening in Ni-Mn-Ga alloys
The TA2 phonon dispersion curves of Ni-Mn-Ga alloys with different compositions which transform to different martensitic structures have been measured over a broad temperature range covering both paramagnetic and ferromagnetic phases. The branches show an anomaly (dip) at a wave number that depends on the particular martensitic structure, and there is softening of these anomalous phonons with d...
متن کاملElectronic structure and magnetism of disordered bcc Fe alloys
We here study electronic structure and magnetic properties of disordered bcc CoxFe1−x, CrxFe1−x and MnxFe1−x alloys in their ferromagnetic phases using Augmented Space Recursion (ASR) technique coupled with tight-binding linearized muffin tin orbital (TB-LMTO) method. We calculate the densities of states, magnetic moments and Curie temperatures of these alloys to show the variation upon alloyin...
متن کاملMagnetic domains in magnetostrictive Fe–Ga alloys
Lorentz microscopy was applied to the observation of magnetic domains in iron-gallium (Fe–Ga) alloys. Results did not show any link between the magnetic domains and the magnetostriction enhancement by Ga addition, but did reveal that the drastic decrease in magnetostriction for Fe–31.2 at. % Ga was due to the presence of large scale precipitates. Magnetic domain features did not change in the a...
متن کاملTwin nucleation in Fe-based bcc alloys—modeling and experiments
We develop an analytical expression for twin nucleation stress in bcc metal and alloys considering generalized planar fault energy and the dislocations bounding the twin nucleus. We minimize the total energy to predict the twinning stress relying only on parameters that are obtained through atomistic calculations, thus excluding the need for any empirical constants. We validate the present appr...
