This book was released on 2014 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microstructure plays a major role in the corrosion of engineering metals and alloys, particularly for aluminium alloys. For any alloy system, microstructure is not well-accounted for when considering electrochemical stability, which is typically described in terms of equilibrium thermodynamics, i.e. Pourbaix diagrams. However, in an engineering context, a likelihood of corrosion as predicted by thermodynamics is not as useful as knowing the kinetic response of reactive metals such as aluminium (i.e. how fast a metal reacts in a certain environment). This work presents a first step towards developing a physical, mechanistic, understanding and representation of kinetic stability for aluminium-based metals, as an engineering alternative to Pourbaix diagrams. The rationale for this is to be able to subsequently compare the impact of 'structural' features, which are not presently considered in equilibrium thermodynamics - however such features are critical to engineering materials. Three key microstructural heterogeneities are studied as model structural variables. This includes: the presence of differing grain boundary density, different number density of precipitates, and varying degrees of crystallinity. To accompany the electrochemical studies, a range of careful specimen preparation and microstructural characterisation has been carried out.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Aluminum and aluminum alloys are widely used for aircraft structures, where they are subjected to demanding conditions and where is an increased demand for weight reduction and fuel savings. Aluminum comprises 8% of the earth?s crust and is, therefore, the most abundant structural metal. Its production since 1965 has surpassed that of copper and now comes next to iron. This increased use of aluminum alloys leads to a need for deeper understanding of their mechanical properties and the impacts of processing parameters. The mechanical properties can determine by controlling the microstructures of the alloys. For example, precipitation hardening is the main strengthening mechanism improving the tensile and yield strength. Solute atoms, precipitates and dispersoids influences to the yield strength, since they act as distributed pinning points for mobile dislocations, thus increasing the shear stress required to move the dislocations. Another approach is the manipulation of a grain size that can be performed by alloying or plastic deformation processes. Therefore, the precise understanding of each mechanism that can influence the properties of aluminum and its alloys is very important. The aim of this chapter is to shed light on the influence of the processing history on the microstructure and mechanical properties.

Available in PDF, EPUB and Kindle. Book excerpt: This text is a companion volume to Transmission Electron Microscopy: A Textbook for Materials Science by Williams and Carter. The aim is to extend the discussion of certain topics that are either rapidly changing at this time or that would benefit from more detailed discussion than space allowed in the primary text. World-renowned researchers have contributed chapters in their area of expertise, and the editors have carefully prepared these chapters to provide a uniform tone and treatment for this exciting material. The book features an unparalleled collection of color figures showcasing the quality and variety of chemical data that can be obtained from today’s instruments, as well as key pitfalls to avoid. As with the previous TEM text, each chapter contains two sets of questions, one for self assessment and a second more suitable for homework assignments. Throughout the book, the style follows that of Williams & Carter even when the subject matter becomes challenging—the aim is always to make the topic understandable by first-year graduate students and others who are working in the field of Materials Science Topics covered include sources, in-situ experiments, electron diffraction, Digital Micrograph, waves and holography, focal-series reconstruction and direct methods, STEM and tomography, energy-filtered TEM (EFTEM) imaging, and spectrum imaging. The range and depth of material makes this companion volume essential reading for the budding microscopist and a key reference for practicing researchers using these and related techniques.
