Available in PDF, EPUB and Kindle. Book excerpt: Volume is indexed by Thomson Reuters BCI (WoS). This book comprises state-of-the–art reviews written by acknowledged experts who are active in sintering science. It includes seven invited reviews by authors hailing from five countries: J-M.Chaix (France) discusses quantitative aspects of the microstructures and modeling of sintering; with the technical aspects of image-analysis - including that of nanostructured materials - adding extra value. Z.S. Nikolic (Serbia) provides a theoretical review of the simulation of liquid-phase sintering, particularly under microgravity conditions, and extensively and critically reviews the results reported in the sintering literature. A.L. Lisovsky (Ukraine) opens up the vista of deconsolidation of polycrystalline skeletons in sintered composite materials, and deals with systems having more than one refractory solid phase, and with nanodispersed composite materials. G.S. Upadhyaya ( India) reviews the Samsonov model for the electronic mechanism of sintering, and its relevance; pointing out that, although the model is a qualitative one, it has great utility as a predictive tool and that various case-studies drawn from real multi-phase material systems are a testimony to the value of Samsonov’s model.

Available in PDF, EPUB and Kindle. Book excerpt: Sintering is a method for manufacturing components from ceramic or metal powders by heating the powder until the particles adhere to form the component required. The resulting products are characterised by an enhanced density and strength, and are used in a wide range of industries. Sintering of advanced materials: fundamentals and processes reviews important developments in this technology and its applicationsPart one discusses the fundamentals of sintering with chapters on topics such as the thermodynamics of sintering, kinetics and mechanisms of densification, the kinetics of microstructural change and liquid phase sintering. Part two reviews advanced sintering processes including atmospheric sintering, vacuum sintering, microwave sintering, field/current assisted sintering and photonic sintering. Finally, Part three covers sintering of aluminium, titanium and their alloys, refractory metals, ultrahard materials, thin films, ultrafine and nanosized particles for advanced materials.With its distinguished editor and international team of contributors, Sintering of advanced materials: fundamentals and processes reviews the latest advances in sintering and is a standard reference for researchers and engineers involved in the processing of ceramics, powder metallurgy, net-shape manufacturing and those using advanced materials in such sectors as electronics, automotive and aerospace engineering. Explores the thermodynamics of sintering including sinter bonding and densification Chapters review a variety of sintering methods including atmosphere, vacuum, liquid phase and microwave sintering Discusses sintering of a variety of materials featuring refractory metals, super hard materials and functionally graded materials

Available in PDF, EPUB and Kindle. Book excerpt: The proceedings of the 4th International Conference on Sin tering and Related Phenomena, contained in this volume, have been broadened in scope to include the phenomena of sintering and coa lescence of catalytic materials dispersed upon refractory oxides. For it has long been recognized within the circles of chemists and chemical engineers working in the field of catalysis that one of the chief causes of the decline in heterogeneous catalytic activity and/or selectivity is, indeed sintering, or perhaps using a better term, coalescence of the supported catalytic metal and compounds thereof. Essentially catalytic deactivation by sintering is now weIl recognized as Ostwald ripening; which of course is a phenome non familiar to scientists grappling with the problem of sintering of powder compacts. The 4th Conference at Notre Dame marks the first occasion at which scientists and engineers of each discipline were assembled in the same room to exchange views on these phenome na of mutual concern. In the wake of the Conference at Notre Dame, all parties acknowledged the synergistic benefit which issued from this exchange, both at the formal and informal level. All were persuaded that signal benefits will be realized by a continuation of this collab oration in the form of future sintering conferences in which both powder metallurgists and catalytic scientists and engineers would participate.

This book was released on 1971 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method was developed to prepare high purite, highly uniform, very reactive, small, under 100A crystallite size ceramic powders. The method consists of preparing a water sensitive organo-metallic compound, preferably an alkoxide, and decomposing it by hydrolysis. The hydroxide is then washed using high purity water or alcohol, dried, ball milled, and finally calcined at 550C. By varying the treatment of the hydroxide, two different types of powders, A and B, were obtained. Powder A is suited for hot pressing consolidation, and pwder B for cold pressing and sintering. The method was specifically developed for the large scale preparation of zirconium oxide containing 6.5 mole % yttrium oxide (Zyttrite). However, a similar process was successfully applied o other ceramic materials such as ferrites, and PLZT, lead lanthanum zirconate titanate. In conjunction with development of the production method, the properties of both type A and B Zyttrite were studied to determine which were important to its capacity for sintering. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The report summarizes an investigation of the influence of deviations from stoichiometry on the sintering of the defect oxide, CoO. The eleven conclusions reached in this investigation are listed in this report and among them are: (1) CoO sinters according to volume diffusion kinetics in the initial and intermediate stages, (2) The sintering rate is increased with increasing oxygen partial pressure above 0.001 atmosphere, (3) The calculated volume diffusion coefficients lie between the tracer values for Co and O in single crystals.

Available in PDF, EPUB and Kindle. Book excerpt: Very fine grained, highly dense, pure alumina prepared by higher pressure sintering in graphite dies shows strengths which are less than would be predicted on the basis of decreasing grain size. Such structures appear to be densely packed but with weakly bonded grains, as evidenced by predominantly intergranular fractures. Preliminary results show strengths in excess of 90,000 to 110,000 psi for pure alumina prepared by ceramic die pressure sintering, even with 3% porosity. Creep studies of dense, pure, fine grained alumina revealed a transition in strain rate - stress dependence at about 2000 psi from a linear to a square dependence. An activation energy of 167 k cals/mol was found. Calculated diffusion coefficients were several orders of magnitude higher than self-diffusion values. An additional vacancy creation creep mechanism was suggested which would be independent of and supplement creep due to self-diffusion, to explain the high coefficients and high activation energy.
