Environmentally assisted fatigue crack nucleation in Ti–6Al–2Sn–4Zr–6Mo
TL;DR: In this article, an unexplained feature was observed at the fatigue crack origin of a number of α / β titanium specimens tested at 450°C in the low cycle fatigue regime, the origin was discoloured blue but this was not a result of temper colouration; this feature sometimes resulted in large reductions in fatigue lives.

An electrochemical model for hot-salt stress-corrosion of titanium alloys
TL;DR: In this paper, an electrochemical model of hot-salt stress-corrosion cracking of titanium alloys is proposed to correlated the diverse observations made concerning this process, and an oxygen-concentration cel exists between the exposed surface of the corrosion specimen and shielded areas such as under salt crystals and at crack tips.
