Training-induced criticality in martensites.
We propose an explanation for the self-organization towards criticality observed in martensites during the cyclic process known as "training." The scale-free behavior originates from the interplay between the reversible phase transformation and the concurrent activity of lattice defects. The basis of the model is a continuous dynamical system on a rugged energy landscape, which in the quasistat...
متن کاملAdaptive modulations of martensites.
Modulated phases occur in numerous functional materials like giant ferroelectrics and magnetic shape-memory alloys. To understand the origin of these phases, we employ and generalize the concept of adaptive martensite. As a starting point, we investigate the coexistence of austenite, adaptive 14M phase, and tetragonal martensite in Ni-Mn-Ga magnetic shape-memory alloy epitaxial films. We show t...
متن کاملNomenclature of Martensites in γ-Phase Alloys
The paper discuss the nomenclature of martensites in the P-phase alloys and proposes to continue to use the current nomenclature with emphasis on the correct interpretations in terms of stacking sequence of the basal planes and the true symmetry of the martensite structure. In their paper "New description of Long Period Stacking Order Structures of Martensites in J3-Phase Alloys" Otsuka et al [...

متن کاملMobility of Domain Walls in Proper Ferroelastic Martensites
Based on the Landau-Ginzberg free energy functional for an Oh-D4h proper ferroelastic martensitic transformation the mobility of a (I 10) twin boundary in a large bicrystal has been calculated by including dissipation in the approximation of the phonon viscosity model and by solving the inverse boundary value problem for the limiting case of strong shear modulus softening. Application to actual...
