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

This paper describes synthesis in 5Ti + 3Si + Al( %) 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 Al titanium silicide and those based on Ti(Al Si aluminide titanium. [ABSTRACT FROM AUTHOR]
