摘要

摘要本文介绍了5Ti + 3Si + \(x\) Al(\(x = 0{-}40\)%) activated mixtures and in an 5Ti + 3Si + 10% Al initial mixture. The effect of mechanical activation and aluminum content on burning rate, maximum combustion temperature, morphology, elongation, integrity, and phase composition of combustion products is studied. Mechanical activation expands the limit of Al content to 40% at which samples can burn without preheating. The following intermetallic alloys are synthesized on the basis of Ti–Si–Al: solid solutions based on Ti(Si\(_{0.75}\)Al\(_{0.25})_{2 }\) titanium silicide and those based on Ti(Al\(_{0.9}\)Si\(_{0.1})_{3}\) aluminide titanium.

Effect of Aluminum Content and Mechanical Activation on Ti–Si–Al Synthesis

Abstract

This paper describes synthesis in 5Ti + 3Si + \(x\)Al(\(x = 0{-}40\)%) activated mixtures and in an 5Ti + 3Si + 10% Al initial mixture. The effect of mechanical activation and aluminum content on burning rate, maximum combustion temperature, morphology, elongation, integrity, and phase composition of combustion products is studied. Mechanical activation expands the limit of Al content to 40% at which samples can burn without preheating. The following intermetallic alloys are synthesized on the basis of Ti–Si–Al: solid solutions based on Ti(Si\(_{0.75}\)Al\(_{0.25})_{2 }\) titanium silicide and those based on Ti(Al\(_{0.9}\)Si\(_{0.1})_{3}\) aluminide titanium.

期刊介绍： Combustion, Explosion, and Shock Waves a peer reviewed journal published in collaboration with the Siberian Branch of the Russian Academy of Sciences. The journal presents top-level studies in the physics and chemistry of combustion and detonation processes, structural and chemical transformation of matter in shock and detonation waves, and related phenomena. Each issue contains valuable information on initiation of detonation in condensed and gaseous phases, environmental consequences of combustion and explosion, engine and power unit combustion, production of new materials by shock and detonation waves, explosion welding, explosive compaction of powders, dynamic responses of materials and constructions, and hypervelocity impact.
