Article Preview

The effects of solution treatment time and artificial aging on the work hardening characteristics on Al-7%Si-0.6%Mg (D357) alloy castings were investigated. Four different solution treatment times at 540°C (1, 4, 16 and 64 hours) and six different artificial aging times at 160°C (0, 2.5, 5, 10, 20 and 40 hours) were used. Work hardening characteristics were investigated by Kocks-Mecking plots for each specimen. The effects of Si particle morphology (solution treatment) and matrix strength (aging) on Kocks-Mecking (Stage III) work hardening model parameters are discussed in the paper.
