Stress-assisted grain growth in nanocrystalline metals: Grain boundary mediated mechanisms and stabilization through alloying
The mechanisms of stress-assisted grain growth are explored using molecular dynamics simulations of nanoindentation in nanocrystalline Ni and Ni-1 at.% P as a function of grain size and deformation temperature. Grain coalescence is primarily confined to the high stress region beneath the simulated indentation zone in nanocrystalline Ni with a grain size of 3 nm. Grain orientation and atomic dis...
متن کاملStress-Driven Surface Topography Evolution in Nanocrystalline Al Thin Films
In their as-fabricated state, nanocrystalline (nc) materials, consisting of individual grains or crystallites with diameters less than 100 nm, are systems that exist far from equilibrium. The large volume fraction of grain boundaries (GB) present in these materials contains considerable excess free energy, which provides a large driving force for grain growth. Grain growth in nc materials has b...
متن کاملThe Role of Confinement on Stress-Driven Grain Boundary Motion in Nanocrystalline Aluminum Thin Films
3D molecular dynamics simulations are performed to investigate the role of microstructural confinement on room temperature stress-driven grain boundary (GB) motion for a general population of GBs in nanocrystalline Al thin films. Detailed analysis and comparison with experimental results reveal how coupled GB migration and GB sliding are manifested in realistic nanoscale networks of GBs. The pr...
متن کاملEffect of Compressive Residual Stress on the Corner Crack Growth
In the present study, plasticity induced crack closure (PICC) concept and three dimensional (3D) finite element methods (FEM) are used to study the effect of compressive residual stress field on the fatigue crack growth from a hole. To investigate the effect of compressive residual stress on crack opening levels and crack shape evolution, Carlson’s experiments were simulated. Crack shape evolut...
متن کاملIrradiation effects on microstructure change in nanocrystalline ceria â•fiPhase, lattice stress, grain size and boundaries
With a wide variety of applications in numerous industries, ranging from biomedical to nuclear, ceramics such as ceria are key engineering materials. It is possible to significantly alter the materials functionality and therefore its applications by reducing the grain size to the nanometer size regime, at which point the unique varieties of grain boundaries and associated interfaces begin to do...
