This book was released on 2012 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of low fracture toughness and the difficulties to densify has delayed the application of boron suboxide (B6O) materials as superhard materials in the industry. Therefore, in this book, efforts have been directed towards improving the fracture toughness and densification of these materials by incorporating suitable secondary phases. Possible candidates are transition metals, which form under sintering conditions a liquid phase. Therefore different Co containing additives (metal, oxide & boride) were used to densify boron suboxide powder by hot pressing. The resulting materials have a strongly improved fracture toughness (3.9 MPam1/2) and still high hardness (HV5=28.6 GPa.).

This book was released on 2012 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: The search for suitable additives for boron suboxide (B6O) materials which could improve densification, reduce sintering temperature and tailor the microstructure has been of great importance. B6O materials doped with 0-5 vol% cobalt addition were sintered at temperatures up to 1850oC and pressure of 50MPa for 20mins. Relationship among the formed phases, microstructures and mechanical properties of the sintered materials was investigated as a function of sintering conditions and added cobalt content. The hardness of the sintered B6O materials increases with sintering temperature, while it decreases with increase in cobalt content. The reverse is also true for the fracture toughness.

Download or read book Boron Rich Solids written by Nina Orlovskaya and published by Springer Science & Business Media. This book was released on 2010-10-07 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this book is to discuss the current status of research and development of boron-rich solids as sensors, ultra-high temperature ceramics, thermoelectrics, and armor. Novel biological and chemical sensors made of stiff and light-weight boron-rich solids are very exciting and efficient for applications in medical diagnoses, environmental surveillance and the detection of pathogen and biological/chemical terrorism agents. Ultra-high temperature ceramic composites exhibit excellent oxidation and corrosion resistance for hypersonic vehicle applications. Boron-rich solids are also promising candidates for high-temperature thermoelectric conversion. Armor is another very important application of boron-rich solids, since most of them exhibit very high hardness, which makes them perfect candidates with high resistance to ballistic impact. The following topical areas are presented: •Boron-rich solids: science and technology •Synthesis and sintering strategies of boron rich solids •Microcantilever sensors •Screening of the possible boron-based thermoelectric conversion materials; •Ultra-high temperature ZrB2 and HfB2 based composites •Magnetic, transport and high-pressure properties of boron-rich solids •Restrictions of the sensor dimensions for chemical detection •Armor
