Book Description
Recent research on solid oxide fuel cell technologies -- a type of high temperature fuel cell -- has resulted in the reduction of operating temperatures from around 1000°C to an intermediate range of 600-800°C. This reduction in temperature allows previously unviable materials to be investigated for use with this system. Interconnects, the component that separates the anode and cathode of adjacent fuel cells, benefit from this advancement as metals may now be utilized in place of the ceramic interconnects traditionally used in solid oxide fuel cell systems. In separating the anode and cathode, interconnects are necessarily subjected to what is known as dual atmosphere exposure: the exposure to the fuel, H 2, on one side of the material and the oxidant, air, on the other side. These extreme operating conditions have unusual effects on materials. AISI 441 is one promising ferritic stainless steel alloy for use as an interconnect; however, under dual atmosphere exposure, AISI 441 sees accelerated and anomalous oxide growth, exceeding that of similar ferritic stainless steels. This study investigated the oxide and Laves phase precipitate evolution of AISI 441 subjected to various environments including single, dual, and vacuum environments at a temperature of 800°C. Additionally, the relationship between the precipitates and the oxide formation was observed. Analysis was performed with a variety of equipment including a field emission scanning electron microscope. In environments containing oxygen, the oxide thickness of AISI 441 was found to increase over time and saw accelerated oxide formation in the dual atmosphere test, corroborating previous research. This study went on to investigate the formation of Laves phase precipitate Fe 2Nbin the microstructure of AISI 441 as a result of atmosphere. Laves phase materials are under research as hydrogen storage materials, suggesting the existence of these phases may facilitate hydrogen transport and storage in materials used as interconnects. Increased hydrogen transport could potentially explain the accelerated and anomalous oxidation of AISI 441 compared to other ferritic stainless steels. Over the time frames tested, the environments had no apparent effect on the Laves phase precipitation; further testing should investigate Laves phase precipitation between 0 and 1000 minutes.

Book Description
George Lai's 1990 book, High-Temperature Corrosion of Engineering Alloys, is recognized as authoritative and is frequently consulted and often cited by those in the industry. His new book, almost double in size with seven more chapters, addresses the new concerns, new technologies, and new materials available for those engaged in high-temperature applications. As we strive for energy efficiency, the realm of high-temperature environments is expanding and the need for information on high temperature materials applications was never greater. In addition to extensive expansion on most of the content of the original book, new topics include erosion and erosion-corrosion, low NOx combustion in coal-fired boilers, fluidized bed combustion, and the special demands of waste-to-energy boilers, waste incinerators, and black liquor recovery boilers in the pulp and paper industry. The corrosion induced by liquid metals is discussed and protection options are presented.

Book Description
A straightforward treatment describing the oxidation processes of metals and alloys at elevated temperatures. This 2006 second edition retains the fundamental theory but incorporates advances made in understanding degradation phenomena. The first half provides an authoritative introduction to the basic principles, covering thermodynamics and mechanisms of high temperature corrosion of metals and alloys. The latter half extends the discussion to oxidation processes in complex systems, from reactions in mixed environments to protective techniques, including coatings and atmosphere control. The authors provide a logical and expert treatment of the subject, producing a revised edition that will be a comprehensive guide to material scientists and engineers requiring an understanding of this elementary process.

Book Description
The 3rd edition of this successful textbook continues to build on the strengths that were recognized by a 2008 Textbook Excellence Award from the Text and Academic Authors Association (TAA). Materials Chemistry addresses inorganic-, organic-, and nano-based materials from a structure vs. property treatment, providing a suitable breadth and depth coverage of the rapidly evolving materials field — in a concise format. The 3rd edition offers significant updates throughout, with expanded sections on sustainability, energy storage, metal-organic frameworks, solid electrolytes, solvothermal/microwave syntheses, integrated circuits, and nanotoxicity. Most appropriate for Junior/Senior undergraduate students, as well as first-year graduate students in chemistry, physics, or engineering fields, Materials Chemistry may also serve as a valuable reference to industrial researchers. Each chapter concludes with a section that describes important materials applications, and an updated list of thought-provoking questions.

Book Description
This is the second volume of an advanced textbook on microstructure and properties of materials. (The first volume is on aluminum alloys, nickel-based superalloys, metal matrix composites, polymer matrix composites, ceramics matrix composites, inorganic glasses, superconducting materials and magnetic materials). It covers titanium alloys, titanium aluminides, iron aluminides, iron and steels, iron-based bulk amorphous alloys and nanocrystalline materials.There are many elementary materials science textbooks, but one can find very few advanced texts suitable for graduate school courses. The contributors to this volume are experts in the subject, and hence, together with the first volume, it is a good text for graduate microstructure courses. It is a rich source of design ideas and applications, and will provide a good understanding of how microstructure affects the properties of materials.Chapter 1, on titanium alloys, covers production, thermomechanical processing, microstructure, mechanical properties and applications. Chapter 2, on titanium aluminides, discusses phase stability, bulk and defect properties, deformation mechanisms of single phase materials and polysynthetically twinned crystals, and interfacial structures and energies between phases of different compositions. Chapter 3, on iron aluminides, reviews the physical and mechanical metallurgy of Fe3Al and FeAl, the two important structural intermetallics. Chapter 4, on iron and steels, presents methodology, microstructure at various levels, strength, ductility and strengthening, toughness and toughening, environmental cracking and design against fracture for many different kinds of steels. Chapter 5, on bulk amorphous alloys, covers the critical cooling rate and the effect of composition on glass formation and the accompanying mechanical and magnetic properties of the glasses. Chapter 6, on nanocrystalline materials, describes the preparation from vapor, liquid and solid states, microstructure including grain boundaries and their junctions, stability with respect to grain growth, particulate consolidation while maintaining the nanoscale microstructure, physical, chemical, mechanical, electric, magnetic and optical properties and applications in cutting tools, superplasticity, coatings, transformers, magnetic recordings, catalysis and hydrogen storage.
