Recent developments in materials science have increased the interest towards the bulk (energetic/energy) materials and the technologies for their production. The unique properties which are typical for the composites fabricated in Ti-Al-B-C systems makes them very attractive for aerospace, power engineering, machine and chemical applications. In addition, aluminum matrix composites (AMCs) have great potential as structural materials due to their excellent physical, mechanical and tribological properties. Because of good combinations of thermal conductivity and dimensional stability AMCs are found to be also potential materials for electronic packaging/application. The methodology/technology for the fabrication of bulk materials from ultrafine-grained powders of Ti-Al-B-C system are described in this paper. It includes results of theoretical and experimental investigation for selection of powder compositions, determination of thermodynamic conditions for blend preparation and optimal technological parameters for mechanical alloying and adiabatic compaction. For consolidation of mixtures the explosive compaction technology was applied at room temperatures.
