In this study, TRA has examined the possibility of using alumina and/or thoria for dispersion hardening of aluminum base alloys. Thoria apparently is not wetted by the aluminum alloy, and hence does not appear to be a candidate for the intended use. On the other hand, alumina is wetted and has been dispersed in a submicron state. The opportunity to produce aluminum alloys with superior high temperature strength is real. The conditions for wetting submicron alumina into a molten alloy of aluminum-copper-magnesium have been demonstrated. This was accomplished by adding copper-alumina master mix slugs to molten aluminum-magnesium. The alloy containing the dispersed oxide was cast and the resulting metal analysed by electron microscopy and hardness after working followed by annealing. Hardness showed retention of properties of annealing. The micrographs showed alumina dispersed uniformly throughout the cast structure at an interparticle (IPS) spacing in the range of 150-200 millimicrons. This is even smaller than the spacing of particles in TD Nickel. Control of IPS at any level from 100 millimicrons and up has been demonstrated. The new alloy, called oxide dispersion strengthened aluminum or ODS aluminum, is expected to have useful metallurgical strength, at 500-550 C, and thus increase the useful temperature range of aluminum base alloys by at least 200 centigrade degrees.

This book discusses several new, near-net-shape techniques for fabricating highly reliable, high-performance, complex ceramic parts. In the context of materials design, the creation of high-performance ceramic products of desired shapes has led to the need for new ceramic forming processes. The near-net-shape techniques combine both injection-molding and colloidal-forming processes. Reviewing and summarizing the research and latest advances, the book is divided into 6 parts: (1) the basic theory, development, and application of the colloidal injection molding of ceramics; (2) the tape casting technology; (3) the reliability of the product; (4) the colloidal injection molding of Si3N4 and SiC; (5) low-toxicity systems; and (6) the novel in-situ coagulation casting of ceramic suspensions via controlled release of high-valence counter ions and dispersant removal. It is intended for researchers and graduates in materials science and engineering.

Colloidal processing has always been a major processing method. It facilitates control of particle interactions through a wide variety of schemes, which include surface coating, dispersion additives, and solvent control, among others. Controlling particle interactions also permits better resultant rheology and controlled green microstructures via a wide range of forming methods. In recent years, the particle size involved has been broadened into both the nanometer and the larger than micrometer ranges. This book covers fundamental issues encountered in colloidal processing nano-(less than 0.1 micron), micro-(from 0.1 to 5 micron) and macro-(larger than 5 micron) particulate systems and at the same time explore applications for these developments.

Many believe that the silicon/information age is heading to the Age of Biology and that the next frontier in ceramics will most likely require molecular level or nanoscale control. What, then, is the role of ceramics in the age of biology? As we change from an energy-rich society to an energy-declining society, how can ceramic materials appease the

The use of colloidal processing principles in the formation of ceramic materials is well appreciated for developing homogeneous material properties in sintered products, enabling novel forming techniques for porous ceramics or 3D printing, and controlling microstructure to enable optimized material properties. The solution processing of electronic ceramic materials often involves multiple cationic elements or dopants to affect microstructure and properties. Material stability must be considered through the steps of colloidal processing to optimize desired component properties. This review provides strategies for preventing material degradation in particle synthesis, milling processes, and dispersion, with case studies of consolidation using spark plasma sintering of these systems. The prevention of multication corrosion in colloidal dispersions can be achieved by utilizing conditions similar to the synthesis environment or by the development of surface passivation layers. The choice of dispersing surfactants can be related to these surface states, which are of special importance for nanoparticle systems. A survey of dispersant chemistries related to some common synthesis conditions is provided for perovskite systems as an example. Furthermore, these principles can be applied to many colloidal systems related to electronic and optical applications.
