 This paper investigates the effects of adding different elements, tantalum, titanium, and anadium to a niobium alloy to determine its effectiveness at resisting ionization loss when exposed to high doses of radiation. The results show that the addition of these elements increases the resistance of the alloy to crack formation and decreases the amount of swelling of the near-surface layer. Additionally, the presence of more elements in the alloy reduces the rate of oxidation and subsequent degradation. This article was authored by Sholpan G. Ginnyatova, Karat K.
