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

      摘要
    • 摘要: 研究了加入质量分数0.15%锆对Al-Mg-Si合金时效(170℃×8h)后及在随后保温(250℃)过程中力学性能和组织的影响.结果表明:加入锆后,合金时效硬度值和力学性能均有一定程度的提高;随保温时间的延长,含锆合金硬度比未含锆合金硬度高,且降低趋势缓慢;主要原因是加入锆后形成了Al3Zr弥散相粒子,强化了Al-Mg-Si合金.

       

      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.
