Shrinkage behavior and crack formation during firing have been investigated for Al2O3/Ce-TZP composites that have been fabricated by colloidal rolling and folding. These composites show improved sinterability and sinter isotropically after repeated rolling. Interface instability in rolling creates corrugated interfaces with large layer waviness; therefore, rolling can substantially alleviate th...

In this study, we combine the elastic instability and non-linear rate-dependent phenomena to achieve microstructure tunability in soft layered materials. In these soft composites, elastic instabilities give rise to formation of wrinkles or wavy patterns. In elastic materials, the critical wavelength as well as amplitude at a particular strain level are exclusively defined by the composite micro...

The notion of realized volatility as a model-free measurement of the quadratic variation of the underlying log price process loses its asymptotic validity in the presence of market microstructure noise. Should microstructure contaminations be present, the summing of an increasing number of squared return data (as in the definition of the realized volatility estimator) simply entails increasing ...

The paper analyses in a systematic manner these structural factors of interfaces in relation to their properties that constitute the background of "interface engineering". It is shown that the specific properties of interfaces are related to their structure. A brief description of recent structural models of interfaces is therefore presented. A new concept of interface microstructure composed o...

Deformation microstructure and texture in a cold-rolled austenitic steel 310S with low stacking fault energy (SFE) have been investigated by SEM and TEM. When 310S plates were rolled by 95% in thickness reduction, a remarkable development of the brass-type preferred orientation was confirmed by X-ray diffraction. SEM observations of the specimens with such texture exhibited a layered structure ...

Using a new high frequency quality data set we provide a precise empirical study of the interdealer spot market. We check that the main stylized facts of financial time series are valid for the FX market: fat-tailed distribution of returns, aggregational normality and volatility clustering. We report two standard microstructure phenomena: microstructure noise effects in the signature plot and t...

Semisolid metal (SSM) processing or thixoforming is widely known as a technology that involves the formation of metal alloys between solidus and liquidus temperatures. For the procedure to operate successfully, the microstructure of the starting material must consist of solid near-globular grains surrounded by a liquid matrix and a wide solidus-to-liquidus transition area. Currently, this proce...

The corrosion resistance of electroless nickel (EN) coatings on ferrous substrates is affected by coating porosity. Carbon and iron carbide are present in the microstructure of ferrous alloys. If the sites of carbon and iron carbide are not catalytically active to EN deposition as the rest of substrate surface, there is a possibility of pore formation on these sites. In the present study, the r...

The main problem with cement composites is that they have structural defects, including cracks, holes, and a disordered morphology, which significantly affects their strength and durability. Therefore, the construction of cement composites with defect-free structures and high strength and long durability is an important research topic. Here, by controlling the size and chemical groups of graphe...

Mn–Zn ferrite powders (Mn0.5Zn0.5Fe2O4) were prepared by the nitrate–citrate auto-combustion method and subsequently annealed in air or argon. The effects of heat treatment temperature on crystalline phases formation, microstructure and magnetic properties of Mn–Zn ferrite were investigated by X-ray diffraction, thermogravimetric and differential thermal analysis, scanning electron microscopy a...
