Load and environmental effects on the corrosion behavior of a Ti6AI4V alloy

This paper focuses on the static mechanical behavior of Ti-6A1-4V titanium alloy when exposed to several aggressive environments. Flat samples, with very light notches (i.e. K-t = 1.16), were tested under static loads, in inert environment and aggressive solutions: the samples gage sections were exposed to air and immerged in a NaCl solution (3.5%) and in a methanol solution (95%). The results of this experimental tests were analyzed and then compared with previous data coming from fatigue tests, carried out in paraffin oil, air, 3.5 wt.% NaCl, and in a methanol solution (95%), with the intent to decouple the effect of the alternating load and of the aggressive environment.
