Regulating corrosion resistance of Al-4.5Mg-2.0Zn-0.3Ag alloy via non-isothermal ageing combined with cold rolling
Source abstract
Abstract
The novel processing strategies of non-isothermal ageing (NIA) combined with cold rolling are proposed in this study. Results indicate that the pre-deformation of 20% in pre-deformation and NIA technology is more conducive to improving the corrosion resistance . The NIA and cold rolling technology promotes intermittent precipitation of grain boundary precipitates and higher density of dislocation cells. Therefore, the alloy processed by NIA for 16 h followed by cold rolling represents superior corrosion resistance. Meanwhile, the alloy processed by NIA for 16 h followed by cold rolling presents higher yield strength than that of the alloy treated by pre-deformation and NIA for 16 h.
