Introduction. Combustion synthesis (CS) has emerged as an important technique for the synthesis and processing of advanced ceramics (structural and functional), catalysts, composites, alloys, intermetallics and nanomaterials. In CS, the exothermicity of the redox (reduction–oxidation or electron transfer) chemical reaction is used to produce useful by: COMBUSTION SYNTHESIS OF ADVANCED MATERIALS 83 the reduction combustion synthesis can be considered to be a two-step process, where the first step is a themite reaction: while the second step is the synthesis from elements similar to scheme (1): I a m- 1 with the total heat release, Q = Q, + example of this type of CS is.
Combustion synthesis of refractory and hard powders Combustion synthesis is widely used for preparing refractory and hard powders,and manycarbide,nitride,boride, andoxynitridepow-ders have been prepared by combustion synthesis [18–23].

A wide range of chemical methods exist for the synthesis of ceramic powders and several reviews of the subject are available in the ceramic literature. For convenience, we will consider the methods in three fairly broad categories:(1) solid-state reactions, (2) synthesis from liquid solutions, and (3) vapor-phase Size: KB.
Semi-solid processing (SSP) is a popular near-net-shape forming technology for metals, while its application is still limited in titanium alloy mainly due to its low formability.

Consequently, these solid-state reactions typically result in the formation of aggregates (hard agglomerations) that require a comminution process to reduce the particle size to the micrometre level. Statistical Thermodynamics of Semiconductor Alloys is the consideration of thermodynamic properties and characteristics of crystalline semiconductor alloys by the methods of statistical thermodynamics.
The topics presented in this book make it possible to solve such problems as calculation of a miscibility gap, a spinodal decomposition range, a short-range order. Basics of Mechanical Engineering Mechanical Engineering, as its name suggests, deals with the mechanics of operation of mechanical systems.
