Microstructures composites

For multi-component systems it seems intuitive that single-component diffusion and adsorption data would enable one to predict which component would be selectively passed through a membrane. This is only the case where molecular sieving is observed for all other separations where the molecules interact with one another and with the zeolite framework their behavior is determined by these interactions. Differences in membrane properties such as quahty, microstructure, composition and modification can also play a large role in the observed separation characteristics. In many cases, these properties can be manipulated in order to tailor a membrane for a specific apphcation or separation. 

The original objective of the ISO classification was to issue detailed standards for cemented carbides in terms of microstructure, composition, and properties for quality control and performance reliability. This objective, however, is yet to be realized. Increased emphasis on worldwide implementation of ISO 9000 standards and globalization of manufacturing, may lead the industry-at-large to adopt the ISO classification.

Results of investigations by Favaron et al. (1980) make it clear that the system is less favourable with regard to formation of amorphous alloys. The amorphous state can be obtained free from crystalline material only in a narrow range close to a = 0.30. At other concentrations the amorphous phase is contaminated with crystalline material of the fee structure (ySj) or with the crystalhne phases of the composition LaCu (C,). As indicated in the top part of fig. 79, no amorphous phase is present when x > 0.40. The concentration dependence of Tq and the corresponding transition widths are shown in the main part of fig. 79. Note that there is a similar correspondence between these widths and the microstructural composition of the samples, as was also found for La. Au (fig. 77). 

J) Polymer modification area through in-situ polymerizations, side group modifications, or surface modifications via grafting or coatings, is expected to grow, opening new paths for producing microstructured composite or hybrid materials.

In materials science, the relationship between the properties, microstructure, composition and manufacture is described as tetrahedroid. This chapter discusses the factors of microstructure and composition (rare earth (RE) elements) on the corrosion process of magnesium (Mg) alloy. 

Influences of microstructure, composition and strain rate for SCC of cast alloys are similar to those of wrought alloys. SCC susceptibility is influenced by (i) the presence and distribution of the P-phase, (ii) grain size and (iii) residual stresses. These factors are related to processing (casting or mechanical working) and heat treatment.
