"A Spin-Echo Small Angle Scattering (SESANS) instrument is capable of studying samples containing large inhomogeneities, large in a sense that they extend across the mesoscopic and microscopic domains. Thus, being applicable to samples of polymers, colloids, dairy products, powders, clays, etc. All of this in a simple and more direct way than existing small-angle neutron-scattering instruments. In essence, there is confidence enough to start exploring the real samples - samples that SESANS is made for. The SESANS experiments conducted and presented in this book will bring insight in the relationship between micro- and macroscopics of fine cohesive powders. The aim is to inspire for future research on samples made up of large disordered heterogeneities through discussing many of the correlation functions expected in these systems."--BOOK JACKET.

The recent introduction of the “nano” dimension to pyrotechnics has made it possible to develop a new family of highly reactive substances: nanothermites. These have a chemical composition that is comparable to that of thermites at submillimeter or micrometric granulometry, but with a morphology having a much increased degree of homogeneity. This book discusses the methods of preparation of these energetic nanomaterials, their specific properties, and the different safety aspects inherent in their manipulation.

Overview of diffraction methods applied to the analysis of the microstructure of materials. Since crystallite size and the presence of lattice defects have a decisive influence on the properties of many engineering materials, information about this microstructure is of vital importance in developing and assessing materials for practical applications. The most powerful and usually non-destructive evaluation techniques available are X-ray and neutron diffraction. The book details, among other things, diffraction-line broadening methods for determining crystallite size and atomic-scale strain due, e.g. to dislocations, and methods for the analysis of residual (macroscale) stress. The book assumes only a basic knowledge of solid-state physics and supplies readers sufficient information to apply the methods themselves.

"The Thesis simulates the microstructure of powder-based materials for the Powder-bed Fusion 3D printing processes. The microstructure is created with the Random Ballistic Deposition methodology, which simulates the sedimentation of spherical particles under the influence of an external field. For the bulk of particles of the same size, the packing fraction depends on the inter-particle forces among them. In the Thesis, different contact areas between particles are created to simulate the sintering effects. The specimens of simulated microstructures of different contact areas are produced with a 3D stereolithographic printer. The printed specimens are then subjected to testing for their differences in stress-strain relationships. The Thesis demonstrates the feasibility of using 3D printed specimens to evaluate materials properties. The Thesis recommends future research to develop a relationship between the microstructure and the mechanical properties with precision as a function of the contact areas."--Abstract.

Sintering is the process of forming materials and components from a powder under the action of thermal energy. It is a key materials science subject: most ceramic materials and many specialist metal powder products for use in key industries such as electronics, automotive and aerospace are formed this way. Written by one of the leading experts in the field, this book offers an unrivalled introduction to sintering and sintering processes for students of materials science and engineering, and practicing engineers in industry. The book is unique in providing a complete grounding in the principles of sintering and equal coverage of the three key sintering processes: densification, grain growth and microstructure. Students and professional engineers alike will be attracted by the emphasis on developing a detailed understanding of the theory and practical processes of sintering, the balanced coverage of ceramic and metal sintering, and the accompanying examination questions with selected solutions. Delivering unrivalled depth of coverage on the basis of sintering, science, including thermodynamics and polycrystalline microstructure. Unique in its balanced coverage of the three key sintering elements - densification, grain growth and microstructure. A key reference for students and engineers in materials science and engineering, accompanied by examination questions and selected solutions.
