Self-propagating high-temperature synthesis of high-temperature light refractories

Journal of Engineering Physics and Thermophysics, 1993
Data on the synthesis of light high-temperature refractories of various compositions in the SHS regime are presented. Optimum conditions for the synthesis are determined; the physicochemical properties of the refractories produced are studied.

Self-propagating high-temperature synthesis of nonstoichiometric wüstite

Journal of Alloys and Compounds, 2012
Abstract This paper describes the self-propagating high-temperature synthesis (SHS) of nonstoichiometric Fe x O ( x  = 0.833–1), with particular focus on the effects of nonstoichiometric Fe content and diluent addition on the phase of the SHS product.

Self-propagating high-temperature synthesis of ferrochromium nitride

Steel in Translation, 2009
Ferrochromium nitride obtained by self-propagating high-temperature synthesis is developed as an alloying material for the production of high-purity, corrosion-resistant steel. Self-propagating high-temperature synthesis involves no energy consumption and has no environmental impact. The product has excellent properties.

Self-propagation high-temperature synthesis of bismuth titanate

Powder Technology, 2004
Abstract A series of 20 experiments on the powder production of the ferroelectric Bi4Ti3O12 (BIT) has been performed through self-propagating high-temperature synthesis (SHS), exploring urea (CO(NH2)2) and the polysaccharide ((C6H10O5)n) as fuels. Different experimental conditions such as annealing temperatures, stoichiometric ratios and the use of ...

Acoustic emission during self-propagating high-temperature synthesis

Combustion, Explosion, and Shock Waves, 2013
It was established experimentally that during SHS, reaction systems (Ni-Al, Ti-B, Mo-B, etc.) generated acoustic oscillations in the frequency range from 5 Hz to 1.1 MHz with a pulse power of up to 17 W. It was found that the combustion of different systems is characterized by an individual set of dynamic parameters of acoustic emission in the modes of

Self-propagating high-temperature synthesis of strontium hexaferrite

Combustion, Explosion, and Shock Waves, 1993
We study the relations governing combustion front propagation and the influence of certain factors (relationship of the starting components, relative density of the specimens being synthesized, oxygen gage pressure, and iron powder particle size) on the temperature and velocity of combustion in the systems Fe−Fe2O3−SrO2−O2 and Fe−Fe2O3−SrCO3−O2.

Composites fabricated by self-propagating high-temperature synthesis

Journal of Materials Processing Technology, 2003
Abstract Self-propagating high-temperature synthesis (SHS) is a promising method for the fabrication of composites. However, the products obtained directly from the SHS process are generally porous, which limits the application of SHS. SHS plus dynamic mechanical pressing, which combines synthesis and densification in one step was proposed and was ...
