The nucleation and structure of dislocations created by the nano-indentation GaN samples with dislocation densities ≈103, 106 or 109 ⊥/cm2 were studied in interest learning how can be to relieve mismatch strain ternary nitride films grown on (0001) oriented binary substrates. Using transmission electron microscopy stress analyses assist interpreting data, we determined that pop-ins indenter load vs. penetration depth curves are an avalanche process at stresses well above typical yield...
Diamond-silicon carbide (SiC) polycrystalline composite blends are studied using a computational approach combining molecular dynamics (MD) simulations for obtaining grain boundary (GB) fracture properties and phase field mechanics capturing deformation failure. An authentic microstructure, reconstructed from experimental lattice diffraction data with locally refined discretization in GB regions, is used to probe effects of local heterogeneities on material response simulations. The nominal...
