Evolution of Microstructure in Pure Nickel during Processing for Grain Boundary Engineering

Grain boundary engineered (GBE) materials have improved properties that are associated with the high fraction special Σ3 n boundaries in the microstructure, where n = 1, 2, or 3. Previous experimental studies with high purity nickel before and after GBE thermomechanical processing have shown that the fraction of Σ3 boundaries increased by at least factor of two [1]. Electron backscatter diffrac...

Evolution of microstructure and texture during recovery and recrystallization in heavily rolled aluminum

The annealing behavior of nanostructured aluminum AA1050 prepared by cold rolling to an ultrahigh strain (vM = 6.4) has been investigated using both transmission electron microscopy and electron backscatter diffraction techniques, paying particular attention to changes in microstructure and texture during recovery and their influence on subsequent recrystallization. It is found that coarsening...

Dislocation Avalanche Polycrystalline Nickel

Self-organized criticality (SOC) is widely observed in systems ranging from creep deformation of single crystal ice to the movement of glacier. -The behavior of these SOC systems follows a power law distribution, which is timeand space-scale invariant. Previous phase field simulation of single crystal nickel has shown that plastic flow is characterized by intermittent dislocation avalanches, wh...

Dynamic recrystallization during deformation of polycrystalline ice: insights from numerical simulations.

The flow of glaciers and polar ice sheets is controlled by the highly anisotropic rheology of ice crystals that have hexagonal symmetry (ice lh). To improve our knowledge of ice sheet dynamics, it is necessary to understand how dynamic recrystallization (DRX) controls ice microstructures and rheology at different boundary conditions that range from pure shear flattening at the top to simple she...

Ultrasonic characterization of microstructure evolution during processing

Ultrasonic characterization of microstructure evolution during processing" (2007). Many cold-working processes for polycrystalline metals cause alignment of the grains with a single symmetry axis. This type of microstructure is called fiber texture. The existence of a preferred orientation of the grains has a significant influence on the propagation and scattering of ultrasonic waves, which are...
