Lattice Softening in Fe3Pt Exhibiting Three Types of Martensitic Transformations
We have investigated the relation between the softening of elastic constants and martensitic transformation in Fe3Pt, which exhibits various kinds of martensitic transformation depending on its long-range order parameter S. The martensite phases of the examined alloys are BCT (S = 0.57), FCT1 (S = 0.75, c/a < 1) and FCT2 (S = 0.88, c/a > 1). The elastic constants C′ and C44 of these alloys decr...
متن کاملLattice charge overlap and the elastic limit
The results of a lattice simulation of time-separated charge overlap for the charged pion are discussed. The expected result ∼ exp[−(Eq − mπ)t ] for large charge density overlap time separations, t, is clearly visible in the Fourier transform, indicating that the elastic limit can be achieved at low to medium momentum values on present-sized lattices. The implications of this result for direct ...
متن کاملLattice Charge Overlap: Towards the Elastic Limit
A numerical investigation of time-separated charge overlap measurements is carried out for the pion in the context of lattice QCD using smeared Wilson fermions. The evolution of the charge distribution function is examined and the expected asymptotic time behavior ∼ e −(Eq−mπ)t , where t represents the charge density relative time separation, is clearly visible in the Fourier transform. Values ...
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 کاملLattice dynamics and phonon softening in Ni-Mn-Al Heusler alloys
Inelastic and elastic neutron scattering have been used to study a single crystal of the Ni54Mn23Al23 Heusler alloy over a broad temperature range. The paper reports the experimental determination of the low-lying phonon dispersion curves for this alloy system. We find that the frequencies of the TA2 modes are relatively low. This branch exhibits an anomaly (dip) at a wave numberξ0=1∕3≈0.33, wh...
