Structural phase transformations in metallic grain boundaries.
Structural transformations at interfaces are of profound fundamental interest as complex examples of phase transitions in low-dimensional systems. Despite decades of extensive research, no compelling evidence exists for structural transformations in high-angle grain boundaries in elemental systems. Here we show that the critical impediment to observations of such phase transformations in atomis...
متن کاملBinding Surfaces and Structural Phase Transformations
We have calculated binding surfaces for cla changes (along the Bain path) and changes of the atomic volume of metallic systems undergoing martensitic transformations. We find characteristic differences between the surfaces of nonmagnetic systems (with a close packed low temperature structure) and magnetic systems (with a less close packed low temperature structure). The ab initio calculations h...
متن کاملStripe-like nanoscale structural phase separation in superconducting BaPb1−xBixO3
The phase diagram of BaPb(1-x)Bi(x)O3 exhibits a superconducting dome in the proximity of a charge density wave phase. For the superconducting compositions, the material coexists as two structural polymorphs. Here we show, via high-resolution transmission electron microscopy, that the structural dimorphism is accommodated in the form of partially disordered nanoscale stripes. Identification of ...
متن کاملInteraction between phase transformations and dislocations at the nanoscale. Part 2_ Phase field simulation examples
The complete system of phase field equations for coupled martensitic phase transformations (PTs), dislocation evolution, and mechanics at large strains is presented. Finite element method (FEM) is utilized to solve this system for two important problems. The first one is related to the simulation of shear strain-induced PT at the evolving dislocation pile-ups in a nanosized bicrystal. Plasticit...
متن کاملInteraction between phase transformations and dislocations at the nanoscale. Part 1. General phase field approach
Thermodynamically consistent, three-dimensional (3D) phase field approach (PFA) for coupled multivariant martensitic transformations (PTs), including cyclic PTs, variant– variant transformations (i.e., twinning), and dislocation evolution is developed at large strains. One of our key points is in the justification of the multiplicative decomposition of the deformation gradient into elastic, tra...
