Abstract
The b-21S titanium alloy corresponds to one of the main titanium alloys for structural applications at high temperatures. Its nominal composition is Ti-15Mo-2,7Nb-3Al-0,2Si (% by weight) or near Ti-8Mo-1.5Nb-5,7Al-0.6Si (% atomic). There is no systematic data on the literature on the possible microstructures developed in this alloys; its mechanical properties and oxidation resistance. Par…
