A two-dimensional computer model is presented to study the development of microstructure and crystallographic texture in polycrystalline films growing on amorphous substrates, which often exhibit strong textures. In particular, the analysis focuses on the influence of growth parameters such as the crystal habit, the relative growth rate along different crystal directions, the nucleation density...

This paper investigates the impact of tungsten nanoparticles on microstructure and mechanical properties Al-5Mg alloy. Tungsten concentrations up to 0.5 wt.% led a slight modification alloy microstructure, grain refinement occurred due inhibition crystal growth along boundaries. Dispersion hardening with made it possible increase ultimate strength by Orowan mechanism simultaneous in plasticity ...

1. It is important to quantify eggshell microstructure because it may influence eggshell mechanical properties and could be of importance for eggshell quality assessment. It also provides information about changes in eggshell associated with different hen physiological conditions. 2. This paper describes an alternative methodology which, based on 2D X-ray diffraction, allows eggshell microstruc...

Four dimensional (4D, or 3D plus time) X-ray tomographic imaging of phase changes in materials is quickly becoming an accepted tool for quantifying the development of microstructures to both inform and validate models. However, most of the systems studied have been relatively simple binary compositions with only two phases. In this study we present a quantitative dataset of the phase evolution ...

Adsorption of asphaltenes at the water-oil interface contributes to the stability of petroleum emulsions by forming a networked film that can hinder drop-drop coalescence. The interfacial microstructure can either be liquid-like or solid-like, depending on (i) initial bulk concentration of asphaltenes, (ii) interfacial aging time, and (iii) solvent aromaticity. Two techniques--interfacial shear...
