Numerical modeling of porous ceramics microstructure

Synthesis, Microstructure and Properties of High-Strength Porous Ceramics

AC Microdischarges in Porous Ceramics

Generation of microdischarges inside porous ceramics by AC high voltage has been investigated. Electrical and optical measurements were performed to explore the physical properties of the microdischarges. The effect of pore size, discharge power and gas mixture on the discharge properties and development is described. Introduction Research of various types of non-thermal plasmas generated by el...

Interrogation of Numerical Simulation for Modeling of Flow Induced Microstructure

This paper summarizes our recent efforts using direct numerical simulations to determine microstructural properties of fluidized suspensions of a few particles. We have been studying the motions of a few particles in a viscous fluid by direct numerical simulation at moderate values of the Reynolds number in the 100’s. From these simulations, we find the mechanisms which give rise to lateral mig...

Microstructure of Transparent Strontium Fresnoite Glass-Ceramics

Glass-ceramics grown from a glass of the composition Sr2TiSi2.45O8.9 (STS 45) are analyzed by scanning electron microscopy (SEM) and electron backscatter diffraction (EBSD). Oriented nucleation with the c-axes preferably perpendicular to the surface is detected. A very strong 001-texture is observed after only 10 μm of growth into the bulk, making this the first system in which an orientation p...

Microstructure of spark plasma sintered TiB2 and TiB2–AlN ceramics

In this research study, the effects of aluminum nitride (AlN) additive on the densification behavior and microstructure development of titanium diboride (TiB2) based ceramic matrix composite were investigated. In this way, a monolithic TiB2 ceramic and a TiB2–5 wt% AlN ultrahigh temperature ceramic composite were fabricated by spark plasma sintering (SPS) proces...
