Book Description
Various issues associated with the design and mechanical evaluation of joints of ceramic matrix composites are discussed. The specific case of an affordable, robust ceramic joining technology (ARCJoinT) to join silicon carbide (CG-Nicalon(sup TM)) fiber-reinforced-chemically vapor infiltrated (CVI) silicon carbide matrix composites is addressed. Experimental results are presented for the time and temperature dependence of the shear strength of these joints in air up to 1200 C. From compression testing of double-notched joint specimens with a notch separation of 4 mm, it was found that the apparent shear strength of the joints decreased from 92 MPa at room temperature to 71 MPa at 1200 C. From shear stress-rupture testing in air at 1200 C it was found that the shear strength of the joints decreased rapidly with time from an initial shear strength of 71 to 17.5 MPa after 14.3 hr. The implications of these results in relation to the expected long-term service life of these joints in applications at elevated temperatures are discussed.

Book Description
The last 30 years have seen a steady development in the range of ceramic materials with potential for high temperature engineering applications: in the 60s, self-bonded silicon carbide and reaction-bonded silicon nitride; in the 70s, improved aluminas, sintered silicon carbide and silicon nitrides (including sialons); in the 80s, various toughened Zr0 materials, ceramic matrix composites reinforced with silicon 2 carbide continuous fibres or whiskers. Design methodologies were evolved in the 70s, incorporating the principles of fracture mechanics and the statistical variation and time dependence of strength. These have been used successfully to predict the engineering behaviour of ceramics in the lower range of temperature. In spite of the above, and the underlying thermodynamic arguments for operations at higher temperatures, there has been a disappointing uptake of these materials in industry for high temperature usc. Most of the successful applications are for low to moderate temperatures such as seals and bearings, and metal cutting and shaping. The reasons have been very well documented and include: • Poor predictability and reliability at high temperature. • High costs relative to competing materials. • Variable reproducibility of manufacturing processes. • Lack of sufficiently sensitive non-destructive techniques. With this as background, a Europhysics Industrial Workshop sponsored by the European Physical Society (EPS) was organised by the Netherlands Energy Research Foundation (ECN) and the Institute for Advanced Materials of the Joint Research Centre (JRC) of the EC, at Petten, North Holland, in April 1990 to consider the status of thermomechanical applications of engineering ceramics.

Book Description
Global population growth and tremendous economic development has brought us to the crossroads of long-term sustainability and risk of irreversible changes in the ecosystem. Energy efficient and ecofriendly technologies and systems are critically needed for further growth and sustainable development. While ceramic matrix composites were originally developed to overcome problems associated with the brittle nature of monolithic ceramics, today the composites can be tailored for customized purposes and offer energy efficient and ecofriendly applications, including aerospace, ground transportation, and power generation systems. The 9th International Conference on High Temperature Ceramic Matrix Composites (HTCMC 9) was held in Toronto, Canada, June 26-30, 2016 to discuss challenges and opportunities in manufacturing, commercialization, and applications for these important material systems. The Global Forum on Advanced Materials and Technologies for Sustainable Development (GFMAT 2016) was held in conjunction with HTCMC 9 to address key issues, challenges, and opportunities in a variety of advanced materials and technologies that are critically needed for sustainable societal development. This Ceramic Transactions volume contains a collection of peer reviewed papers from the 16 below symposia that were submitted from these two conferences Design and Development of Advanced Ceramic Fibers, Interfaces, and Interphases in Composites- A Symposium in Honor of Professor Roger Naslain Innovative Design, Advanced Processing, and Manufacturing Technologies Materials for Extreme Environments: Ultrahigh Temperature Ceramics (UHTCs) and Nano-laminated Ternary Carbides and Nitrides (MAX Phases) Polymer Derived Ceramics and Composites Advanced Thermal and Environmental Barrier Coatings: Processing, Properties, and Applications Thermomechanical Behavior and Performance of Composites Ceramic Integration and Additive Manufacturing Technologies Component Testing and Evaluation of Composites CMC Applications in Transportation and Industrial Systems Powder Processing Innovation and Technologies for Advanced Materials and Sustainable Development Novel, Green, and Strategic Processing and Manufacturing Technologies Ceramics for Sustainable Infrastructure: Geopolymers and Sustainable Composites Advanced Materials, Technologies, and Devices for Electro-optical and Medical Applications Porous Ceramics for Advanced Applications Through Innovative Processing Multifunctional Coatings for Sustainable Energy and Environmental Applications
