2.1MATERIALS HAVING PREDOMINANTLY HOMOGENEOUS STRUCTURE AND COMPOSITION There can only be one definition of homogeneity: “homogeneous materialhas every infinitesimal volume of its bulk exactly the same regarding its chemical composition and structure.” This definition differs drastically from its common use...
Fig. 1.(a) A general representation of materials synthesis based on “top-down” and “bottom-up” approaches. (b) The fundamental properties of new materials depend on their physical characteristics such as surface/crystallinity, composition, particle size, shape, agglomeration state, porosity, su...
There is provided a steel material for reinforcement having a predetermined component composition and a metallic structure consisting of, by volume percentage, 85% or more of bainite, 2 to 9% of retained austenite and the balance martensite and having mechanical properties of 0.2% bearing force:785...
The varieties of glass differ widely in chemical composition and in physical qualities. Most varieties, however, have certain qualities in common. They pass through a viscous stage in cooling from a state of fluidity; they develop effects of colour when the glass mixtures are fused with certain ...
