Precipitation in stretched Al-Cu-Mg alloys with reduced alloying content studied by DSC, TEM and atom probe
The hardening and microstructural evolution during ageing of a Al-1.2Cu-0.5Mg and a A1-1.2Cu-1.2Mg (at.%) alloy has been investigated. Artificial ageing at 150degreesC of stretched and naturally aged samples initially (up to about 48 h) leads to very limited further strengthening, but ageing at 190d...
