Evading the strength-corrosion trade-off dilemma of 5xxx aluminum alloys by cyclic plasticity
Source abstract
Abstract
Low-magnesium 5xxx (< 3 wt%) alloys effectively suppress sensitization but have low strength due to limited solid solution strengthening. This study shows that despite the lower driving force and slower precipitation kinetics in low-magnesium 5xxx alloys, applying cyclic plasticity can still enhance their strength through the formation of solute clusters. Additionally, these clusters reduce the concentration of free Mg atoms, effectively mitigating the Portevin-Le Chatelier effect. After sensitization treatment at 70 °C for 2 months, the cyclically strengthened alloys even show improved intergranular corrosion resistance. Applying the CS method to low-magnesium 5xxx alloys can better resolve the strength-corrosion trade-off dilemma.
