This translation from the unique Russian ebook outlines the construction of numerous fabrics through equipment of self-propagating high-temperature synthesis (SHS). the kinds of fabrics mentioned contain: not easy, refractory, corrosion and wear-resistant fabrics, in addition to different complicated and area of expertise fabrics. The authors tackle the difficulty of optimum parameters for SHS reactions taking place in the course of techniques concerning a initial metallothermic relief level, and so they calculate those utilizing thermodynamic methods. with the intention to ensure the effectiveness of this strategy, the authors describe experiments targeting the synthesis of elemental crystalline boron, boron carbides and nitrides. different elements of this short comprise theoretical and experimental effects on single-stage construction of not easy alloys at the foundation of titanium and zirconium borides, in addition to macro kinetics of degassing and compaction of SHS-products. This short is acceptable for lecturers, in addition to these operating in business production businesses generating tough alloys and composites for making metal-working equipment or drilling equipment.
