抄録

This work deals with mechanical properties of the Al-Si-0.15%Sb alloy containing different amounts of Si from 1 to 13% and with effects of Mg and Fe on the mechanical properties of Al-7%Si-Mg alloy. The ultimate and yield strength of Al-Si-0.15%Sb alloy gradually increases with increase in Si content, but the elongation and Charpy impact value rapidly decrease at Si content 6 to 8% or more. The ultimate and yield strength of Al-7%Si-0.2% and Al-7%Si-0.006%Fe alloys exponentially increase with Mg content up to 0.4%. Increase of Mg up to 0.4% rapidly decreases the elongation and impact strength. 0.1 to 0.35%Fe in the Al-7%Si-0.2%Mg alloy provides the maximum ultimate tensile strength, but more of Fe rapidly reduces it. Increase in Fe gradually increases the yield strength, but exponentially reduces the elongation and impact strength.
