Abstract
This paper describes the hydrogen embrittlement (HE) of an Al-Li alloy aged at 190°C and with different durations of ageing (10, 15, 20 and 30 hr). Two techniques were employed to measure HE : a) cathodic polarization in a molten salts bath with -3 V/Ag on tensile specimens ; b) gaseous hydrogenation on disks. Hydrogen charging was achieved at 190°C. The results show that HE is important when the alloy is in the over-aged condition.
