Titanium alloys display low density, high mechanical strength and good corrosion resistance, being ideal structural materials for aerospace engineering. In this paper, the effects of nitrogen on the anelastic properties of the bcc alloy Ti-13V-11Cr-3Al were investigated. The results show an asymmetric thermally activated relaxation structure in the high-temperature region. This relaxation structure was decomposed, and relaxation processes due to stress-induced ordering of nitrogen atoms around the metallic matrix and substitutional solutes were identified.
