On the small angle twist sub-grain boundaries in Ti3AlC2
Tilt-dominated grain boundaries have been investigated in depth in the deformation of MAX phases. In stark contrast, another important type of grain boundaries, twist grain boundaries, have long been overlooked. Here, we report on the observation of small angle twist sub-grain boundaries in a typical MAX phase Ti3AlC2 compressed at 1200 °C, which comprise hexagonal screw dislocation networks fo...
متن کاملasymmetric tilt grain boundaries in fcc metals by atomistic simulations
The shear response of the 3 [1̄ 1 0]-tilt (1̄ 1̄ 5)/(1 1 1) and 9 [1̄ 1 0]-tilt (1 1 5)/(1 1 1) asymmetric tilt grain boundaries (GBs) in fcc metals Cu and Al has been studied by atomistic simulation methods with the embedded atom method interatomic potentials and with a bicrystal model. It is found that the structure of the GBs studied can be well described by the coincidence site lattice (CSL) th...
متن کاملDecay of low-angle tilt boundaries in deformed nanocrystalline materials
A theoretical model is suggested, which describes a decay of low-angle grain boundaries in deformed nanocrystalline materials (NCMs). In the framework of the model, lattice dislocations that form a low-angle boundary are under the action of the forces owing to external (applied) and internal stresses. The balance of the forces causes the critical shear stress at which a low-angle boundary decay...
متن کاملTransition between Low and High Angle Grain Boundaries
Institut für Metallkunde und Metallphysik, RWTH Aachen, 52056 Aachen, Germany Carnegie Mellon University, Pittsburgh PA 15213, USA Abstract The migration of planar, symmetric tilt grain boundaries with different tilt axes was investigated. The driving force for the grain boundary migration was due to an external mechanical stress field. Low as well as high angle grain boundaries can move under ...
متن کاملLiquid nucleation at superheated grain boundaries.
Grain boundaries with relatively low energies can be superheated above the melting temperature and eventually melt by heterogeneous nucleation of liquid droplets. We propose a thermodynamic model of this process based on the sharp-interface approximation with a disjoining potential. The distinct feature of the model is its ability to predict the shape and size of the critical nucleus by using a...
