Ordering kinetics of stripe patterns
, 2001 We study domain coarsening of two dimensional stripe patterns by numerically solving the Swift-Hohenberg model of Rayleigh-Benard convection. Near the bifurcation threshold, the evolution of disordered configurations is dominated by grain boundary motion

Development of the FE In-House Procedure for Creep Damage Simulation at Grain Boundary Level
Metals, 2019 A two-dimensional (2D) finite element framework for creep damage simulation at the grain boundary level was developed and reported. The rationale for the paper was that creep damage, particularly creep rupture, for most high temperature alloys is due to ...

Boundary selectivity of crack paths in corrosion fatigue of stainless steel [PDF]
, 2008 Stress corrosion and corrosion fatigue cracks are frequently very branched and there have been extensive attempts to define the characteristics of crack-stopping features. EBSD has been used to examine the full length (~8mm) of a corrosion fatigue crack

Challenges during Flash Lamp Annealing of Aerosol‐Deposited Barium Titanate Films
Advanced Engineering Materials, EarlyView.Aerosol deposition is used to rapidly deposit barium titanate films with thicknesses ranging from 2 to 16 μm at room temperature, eliminating the need for further densification. However, to recover the electromechanical properties, annealing is required, which limits the usage of temperature‐sensitive substrates.

Grain boundaries in semiconductors
Journal of Physics C: Solid State Physics, 1985 This review presents the available experimental and theoretical understanding on the structure and electronic properties of grain boundaries in semiconducting materials. High-resolution electron microscope images of interfaces are interpreted within the framework of the structural unit model of grain boundaries, and the electronic properties of the ...

Ostwald Ripening of Diffusion-Limited Small-Size Precipitates at Grain Boundaries [PDF]
Журнал нано- та електронної фізики, 2012 The paper describes a theoretical study of the Ostwald ripening of two-dimensional small-size precipitates of a newly formed phase at the grain boundary of finite thickness, taking into account the diffusion of impurity atoms from the grain interior to ...

Advanced Engineering Materials, EarlyView.This study examines how several molten high‐silicon electrical steels interact with both conventional and recycled MgO–C refractories. For this, various immersion experiments are conducted. In addition to infiltration, a number of mechanisms are identified and explained that control the corrosion of the refractory material.
