SOLUTION STRENGTHENING AND AGE HARDENING CAPABILITY OF Al-Mg-Mn ALLOYS WITH SMALL ADDITIONS OF Cu
Nine Al-(1-3)Mg-(0-0.4)Cu-0.15Si-0.25Mn (in wt%) alloys with potential applications in both packaging and automotive industries have been investigated. Tensile testing showed that solution strengthening is in good approximation linearly proportional to the Mg content. Mechanical testing and microstructural examinations of aged samples indicate that Mg2Si phase precipitates contribute to age har...
متن کاملEmbrittlement of Al-Li-Cu-Mg alloys at slightly elevated temperatures: microstructural mechanisms of hardening
When underaged, damage tolerant Al-Li based alloys are exposed to slightly elevated temperatures (60 to 100oC), their strength increases and toughness decreases. To study the first stages of this process, 8090 sheet in three underaged heat treatment conditions, including T3, T81 and a multistage temper, was exposed for 1000 h at 70°C. Using a model for strengthening in combination with a quanti...

متن کاملCASTABILITY OF Al-Li-Mg AND Al-Li-Cu-Mg ALLOYS
The objective of the present work is to study the casting characteristics of various A1-Li alloys, which include fluidity and strengths of the alloys and their interaction with cast molds. Materials investigated are Al-Li-Mg and Al-Li-Cu-Mg alloys with Li content of 2.5 wt%. The results show that sand molds with resin binders are good for A1-Li casting. Ceramic coatings can further reduce the m...
