Nucleation barriers for the cubic-to-tetragonal phase transformation
We are interested in the phase transformation from austenite to martensite. This transformation is typically accompanied by the generation and growth of small inclusions of martensite. We consider a model from geometrically linear elasticity with sharp energy penalization for phase boundaries. Focusing on a cubic-to-tetragonal phase transformation, we show that the minimal energy for an inclusi...
متن کاملNucleation barriers at corners for cubic-to-tetragonal phase transformation
We are interested in the energetic cost of a martensitic inclusion of volume V in austenite for the cubic-to-tetragonal phase transformation. In contrast with the work of [Knüpfer, Kohn, Otto: Comm. Pure Appl. Math. 66 (2013), no. 6, 867–904], we consider domain with a corner and obtain a better scaling law for the minimal energy (Emin ∼ min(V , V )). Our predictions are in a good agreement wit...
متن کاملCritical Integrated Raman Scattering Intensity near the cubic-tetragonal phase transition in Strontium Titanate
Emphasizing the contribution of Professor Roger A Cowley, FRS to the Theory of Raman Scattering from crystals, the development of the Theory of Raman Scattering since 1928 has been briefly discussed. Some experimental studies of Strontium Titanate using Inelastic Neutron Scattering, Raman Scattering, Electro-paramagnetic resonance measurement and X-ray & Gamma Ray techniques has been briefly di...
متن کاملCooperative Jahn–Teller effect and the role of strain in the tetragonal-to-cubic phase transition in MgxCu1 − xCr2O4
Temperature and composition dependences of the I41/amd → [Formula: see text] phase transition in the Mg x Cu1 - x Cr2O4 spinel solid solution, due to the melting of the cooperative Jahn-Teller distortion, have been studied by means of single-crystal X-ray diffraction. Crystals with x = 0, 0.10, 0.18, 0.43, 0.46, 0.53, 1 were grown by flux decomposition methods. All crystals have been refined in...
متن کاملTi3O14: a new family of tunable dielectric oxides showing a compositionally controlled tetragonal to cubic transition
Oxides of the formula Nd2Ba2CaCu2_xZnxTi3Oi4 (x = 0:0, 0.5, 1.0, 1.5, 2.0) have been successfully prepared by high temperature ceramic route at 1025 8C, as well as by the low temperature citrate precursor route at 800 8C. The copper-rich compounds obtained by the ceramic route (x = 0-1.0) are found to have a tetragonal structure, with the a and c parameters increasing with zinc substitution, fr...
