The effect of Si addition on the microstructure and mechanical properties of Al-Mg-Si-Zn aluminum alloys were investigated. Results show that the microstructure of Al-Mg-Si-Zn alloy with low Si contents is mainly composed of Mg2Si and Mg5Si6 phases. With the increasing of Si content. Si and Al3. https://www.bekindtopets.com/quick-buy-Titans-Pets-First-Reversible-Dog-Bandana-deal-zone/
