- Abstract
The influence of natural ageing and plastic deformation on precipitation in an Al–3 wt% Cu–1 wt% Li–(Mg,Ag) alloy is investigated by small‐angle X‐ray scattering. When predeformation is applied before artificial ageing, regardless of natural ageing, the T1 phase precipitates rapidly, resulting in a strong hardening response. When no deformation is applied, the T1 phase precipitates more sluggishly and the strengthening response is lowered.
