Abstract—To obtain a composite with interpenetrating intermetallic/ceramic phases (of type IPC, interpenetrating phase composites) by the self-propagating high-temperature synthesis (SHS) method, the Ni–Al–Ti–2B powder system was used. It consisted of mechanically activated composite particles-granules (Ni + Al) and a mixture of finely dispersed boron and titanium powder. The quantitative ratio between the granules and the Ti + 2B mixture was varied. For all compositions, the synthesis was carried out in the combustion mode without heating. In the combustion wave front, the chemical reactions occurred in the composite granules and in the mixture around the granules, between titanium and boron. As a result of combustion a porous framework of titanium diboride was formed; a melt of nickel aluminides penetrated into the pores of the framework. The metal–ceramic combustion product is characterized by developed porosity and a composite structure with diboride and intermetallic phases located like interpenetrating frameworks. The TiB2–NiAl structure depends on the ratio of components in the mixture. The pores formed in place of the granules, repeating their shape.
期刊介绍：
Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
