<p>Hydrogen embrittlement sensitivity of a high-Zn containing Al–Zn–Mg–Cu series alloy in T6 temper was evaluated by tensile testing at various strain rates in humid air (HA) and dry nitrogen gas (DNG). The elongation of Al–10Zn–2.6Mg–1.6Cu–0.2Cr alloy in HA was smaller than that in DNG due to hydrogen embrittlement. Quasi-cleavage fracture caused a loss of elongation at medium strain rates (10−3–10−4 s−1), and smooth intergranular cracking degraded ductility largely at slow strain rates (10−5–10−6 s−1). These results indicate that the higher content of Zn in Al–Zn–Mg–Cu series alloy increase hydrogen embrittlement sensitivity, and exhibits hydrogen embrittlement even when the strain rate is 10−3 s−1.</p>
