Susceptibility of Ti-6Al-4V alloy to stress corrosion cracking in a Lewis-neutral aluminium chloride-1-ethyl-3-methylimidazolium chloride ionic liquid

Abstract The susceptibility of Ti–6Al–4 V alloy to stress corrosion cracking (SCC) in a Lewis neutral AlCl 3 –EMIC ionic liquid (IL) was investigated employing U-bend tests. The results indicated that cracking initiated at the α/β phase boundary, propagated intergranularly, followed by transgranular cracking and failed in dimple mode under overloaded stress.
