Characterization of the evolution of pores in thermal barrier coatings (TBCs) under volcanic ash (VA) corrosion is essential for assessing coating premature failure. As a nondestructive three-dimensional visualization method, X-ray computed tomograph

To further understand the erosion mechanism of the electron beam physical vapor deposited thermal barrier coatings, the failure mechanism diagrams with different parameters were established by finite element simulations. The effects of various parame

In face-centered-cubic (fcc) metals, the evolution of Shockley partial dislocations under stress is known to play an important role in plastic deformation. The simulations of the dislocation evolutions, including dislocation dissociation, nucleation

The a 0 / 2 〈 111 〉 screw dislocation glides through the nucleation and propagation of the kink-pair which dominates the plastic deformation of the BCC iron. A continuum model and the corresponding numerical methods are developed to investigate t

The growth of thermally grown oxide (TGO) is often regarded as a key factor causing failures of thermal barrier coatings (TBCs) because it leads to thermal cycling and growth stresses. However, the delamination mechanism of TBCs induced by the growth

The thickening mechanism of the deformation twinning (DT) has been frequently studied in numerous researches and the transverse propagation of that is beginning to trigger the attention of scholars. Recently, some researchers report that the twin fro

High temperature ceramic corroded by calcium-magnesium-alumino-silicates (CMAS) deposits is an inevitable part of severe degradation of thermal barrier coatings (TBCs). Based on thermodynamic laws, a mechanism-based constitutive theory is proposed fo

A multiphase field theory and corresponding finite element simulations are developed to describe ferroelastic domain switching in bulk polydomain tetragonal zirconia (t′-zirconia). We consider the ferroelastic switching as mechanical twinning in ou
