Structural Phase Transformation and Phonon Softening in Iron-Based Alloys
The interrelation of Invar and Martensite in iron-based alloys like Fe3Ni is discussed on the basis of ab initio calculations for different crystal structures. Inelastic neutron scattering and ultrasonic experiments have shown that a soft transverse phonon mode in [110] direction acts as a precursor in the close packed fcc phase of these systems. Unfortunately there are no experimental results ...
متن کاملStructural Phase Stability and Electron-Phonon Coupling in Lithium
First-principles calculations of the free energy of several structural phases of Li are presented. The densityfunctional linear-response approach is used to calculate the volume-dependent phonon frequencies needed for computing the vibrational free energy within the quasiharmonic approximation. We show that the transformation from a close-packed structure at low temperatures to the bcc phase up...

متن کاملStructural phase transition in epitaxial perovskite films
Three different film systems have been systematically investigated to understand the effects of strain and substrate constraint on the phase transitions of perovskite films. In SrTiO3 films, the phase transition temperature Tc was determined by monitoring the superlattice peaks associated with rotations of TiO6 octahedra. It is found that Tc depends on both SrTiO3 film thickness and SrRuO3 buff...
متن کاملStructural Phase Transition Accompanied by Metal - Insulator Transition in PrRu4P12
A structural phase transition has been found using electron diffraction technique in PrRu4P12 accompanied by a metal insulator (M I) transition (TMI = 60K). Weak superlattice spots appeared at (H, K, L) (H + K + L = 2n + 1; n is an integer) position at a temperature of T = 12 K and 40 K. Above T = 70 K, the spots completely vanished. The space group of the low temperature phase is probably Pm 3...
