During the past decade, considerable research effort has been directed towards the development of in situ metal matrix composites (MMCs), in which the reinforcements are formed in situ by exothermal reactions between elements or between elements and compounds. Using this approach, MMCs with a wide range of matrix materials (including aluminum, titanium, copper, nickel and iron), and second-phase particles (including borides, carbides, nitrides, oxides and their mixtures) have been produced. Because of the formation of ultrafine and stable ceramic reinforcements, the in situ MMCs are found to exhibit excellent mechanical properties. In this review article, current development on the fabrication, microstructure and mechanical properties of the composites reinforced with in situ ceramic phases will be addressed. Particular attention is paid to the mechanisms responsible for the formation of in situ reinforcements, and for creep failure of the aluminum-based matrix composites.

Combustion synthesis and nanomaterials

Combustion synthesis of advanced materials: Part I. Reaction parameters

A short information is given on the results of work carried out at the Branch of the Institute of Chemical Physics, U.S.S.R. Academy of Sciences, since 1967 on studying the combustion processes caused by the interaction of chemical elements in the condensed phase and leading to the formation of refractory compounds. New phenomena and processes are described which are revealed when investigating the combustion of the systems of this class, viz solid-phase combustion.fast combustion in the condensed phase, filtering combustion, combustion in liquid nitrogen, spinning combustion, self-oscillating combustion and repeated combustion. A new direction in employment of combustion processes is discussed, viz. a self-propagating high-temperature synthesis of refractory nitrides, carbides, borides, silicides and other compounds.

A New Class of Combustion Processes

Historical retrospective of SHS: An autoreview

The paper concerns chemical issues of self-propagating high temperature synthesis. Chemical classes of the SHS processes and products are considered. The results of research into SHS chemistry are discussed according to the classification suggested by the author: solid solutions of nonmetals in metals, binary compounds (carbides, borides, silicides, nitrides, hydrides, oxides, chalcogenides, etc. 1, chemical mechanism of formation in combustion mode, and intermediate products. Single - phase multicomponent SHS systems involving complex carbides, oxides, nitrides, carbonitrides, hydrocarbides, and hydronitrides are also treated. An extended class of the SHS products comprises complex heterogeneous mixtures of refractory inorganic compounds, as well as hard alloys. The reactions used for synthesizing SHS products of different classes are presented. The use of SHS for producing organic and polymer compounds was experimentally shown to be possible. Finally, the discussion of some issues related to the crystalline structure and particle size of SHS products is presented which is important for understanding the process itself, as well as for practical application of SHS compounds of different classes.
