    Effect of Addition Zr on Aging Microstructure and Property of Al-Mg-Si Alloy

      Abstract
    • The effect of addition 0.15% Zr on the mechanical properties and microstructure of Al-Mg-Si alloy after aging treatment(170℃×8h)and holding temperature process(250℃) was studied.The mechanical properties and aging hardness of Al-Mg-Si alloy were improved to some extent.In addition,the hardness curve of the alloy with Zr showed a slower decreasing than that of alloy without Zr with increasing the holding temperature.The main reason was that the Al3Zr dispersoids improved the properties of alloys.
