High-Temperature Borides by T. Serebryakova Download PDF EPUB FB2

UHTCs mainly include transition metal borides (TMBs), carbides, and nitrides, among which ultra-high temperature borides include HfB 2, ZrB 2, TaB 2, and TiB 2, etc. [1] [2][3][4][5][6][7][8. This exhaustive work in three volumes with featuring cross-reference system provides a thorough overview of ultra-high temperature materials – from elements and chemical compounds to Brand: Springer.

The results of an experimental study of the thermodynamic properties of HfB 2, Nb 3 B 2, NbB, Nb 3 B 4, NbBTaBCrBCr B, Mo 2 B, MoBMo 2 B 5, W 2 B, WB and W 2 B 5 at high temperature are summarized.

The temperature coefficients for the enthalpy and heat capacity are by:   Description High Temperature Oxides: Refractory Glasses, Glass-Ceramics, and Ceramics is the fourth part of a series of four books on high temperature oxides.

This book is divided into nine chapters that cover refractory glasses and glass-ceramics, alumina-containing compounds, zinc oxide, tungsten oxide compounds, and slip-casting of Edition: 1.

Metal borides are one of the subgroups of refractory hard materials and can be used in various applications, including the defense, nuclear industry, and high-temperature industries. SHS is one of the common production method for High-Temperature Borides book borides.

With the use of the SHS method, metal boride powders can be obtained at nanoscale without grinding. The first comprehensive book to focus on ultra-high temperature ceramic materials in more than 20 years.

Ultra-High Temperature Ceramics are a family of compounds that display an unusual combination of properties, including extremely high melting temperatures (>°C), high hardness, and good chemical stability and strength at high temperatures. The high-entropy boride powders in published literature were mostly obtained by mechanically alloying via HEBM to refine the particle High-Temperature Borides book and targeting the low-temperature densification of high-entropy boride ceramics.

It is postulated that this methodology could affect the density of the samples in two ways. The performance of material in ultra high temperature environment is determined not only by the properties of borides but also by the high temperature properties of their respective oxides.

ZrO 2 and HfO 2 have high melting point (> o C) and thus ZrB 2 and HfB 2 are superior to other metal borides for the high temperature oxidizing conditions. Post-bond heat treatment (PBHT) applied to a transient liquid phase (TLP) bonding joint is an effective approach to remove the brittle borides and imp.

The PXRD patterns in Fig. 1 were refined to calculate the lattice parameter and the yield of high-entropy boride phase. As shown in Table 1, the lattice parameter of a and c in all compositions was smaller than that in ZrB 2 (a = Å, c = Å []) and HfB 2 (a = Å, c = Å []).Among the calculated values, a very small difference (˜ 1%) in a-parameter was observed.

Objective High Temperature Materials and Processes offers an international publication forum for new ideas, insights and results related to high-temperature materials and processes in science and technology.

The journal publishes original research papers and short communications addressing topics at the forefront of high-temperature materials research including processing of various materials.

This book examines high-temperature materials and mechanisms from many angles. It covers the topics of processes, materials characterization methods, and the nondestructive evaluation and health monitoring of high-temperature materials and structures. It describes the application of high temperature materials to actuators and sensors, sensor Author: Yoseph Bar-Cohen.

Cite this chapter as: Van De Voorde M.H. () High Temperature Corrosion of Silicon Nitrides. In: Freer R. (eds) The Physics and Chemistry of Carbides, Nitrides and Borides. This second volume is dedicated to carbon, refractory metals (W, Re, Os, Ta, Mo, Nb, Ir) and compounds which have melting points around/above C while the first volume focuses on carbon and refractory metals.

The book explains physical and chemical properties. Finally, some high-temperature diffusion-related processes (e.g. sintering, creep, grain growth, etc.) are also treated to some extent.

A new group of ternary borides has been found that show either ferromagnetism or superconductivity. Their general formula is MRh 4 B 4 where M is a transition or rare-earth element.

Their superconducting transition temperatures range from approximately K for the Sm compound to approximately 12 K for the Lu compound.
