Influence of cold work and solutionising temperature on age hardening capability of Al-Mg-Mn alloys with small Cu and Si additions
Influence of cold work and solutionising temperature on age hardening capability of Al-Mg-Mn alloys with small Cu and Si additions
The influence of cold rolling and solution treatment on precipitation in Al-(1-3)Mg-0.25Mn-(0 0.4)Cu-0.15Si (wt%) alloys was investigated. After solutionising at 550°C, all alloys showed age hardening, and differential scanning calorimetry (DSC) confirmed the occurrence of precipitation reaction(s) in each alloy. After solutionising at 500°C, all Cu-containing alloys showed precipitation hardening; for Cu-free alloys, only the alloy with 1wt% Mg showed precipitation hardening, and no substantial precipitation hardening was observed for alloys with Mg content 2wt% or higher. This observed suppression of age hardening with increasing Mg content for Cu-free alloys was analysed with reference to the undissolved Mg2Si intermetallics formed during solution treatment. These intermetallics were characterised using FEG-SEM and EDS. For the age hardening alloys solutionised at 500°C, both the time to peak ageing and the amount of precipitation hardening decrease with increasing cold rolling reduction.

Abstract
The influence of cold rolling and solution treatment on precipitation in Al-(1-3)Mg-0.25Mn-(0 0.4)Cu-0.15Si (wt%) alloys was investigated. After solutionising at 550°C, all alloys showed age hardening, and differential scanning calorimetry (DSC) confirmed the occurrence of precipitation reaction(s) in each alloy. After solutionising at 500°C, all Cu-containing alloys showed precipitation hardening; for Cu-free alloys, only the alloy with 1wt% Mg showed precipitation hardening, and no substantial precipitation hardening was observed for alloys with Mg content 2wt% or higher. This observed suppression of age hardening with increasing Mg content for Cu-free alloys was analysed with reference to the undissolved Mg2Si intermetallics formed during solution treatment. These intermetallics were characterised using FEG-SEM and EDS. For the age hardening alloys solutionised at 500°C, both the time to peak ageing and the amount of precipitation hardening decrease with increasing cold rolling reduction.
