High-Temperature Strength of Titanium Alloys Alloyed with Silicon, Aluminum, and Zirconium in Air

摘要

We study the behavior of VT1-0 titanium alloy alloyed with silicon, aluminum, and zirconium in the process of oxidation in air at 800 deg C for 30 h. It is shown that, as a result of alloying of the alloy with silicon up to 6 wt. percent, its high-temperature strength becomes more than two times higher. This effect is connected with the influence of silicon on the diffusion processes in the metal and scale and changes in the morphology of scale.
