Type: article
Abstract: The microstructure and mechanical properties of aged Mg-5.5Al-1.2Y magnesium alloy with Ca addition are investigated. The results show that with 1.0wt.% Ca addition, the phase of Al2Y is refined obviously and the phase of Mg17Al12has a dramatic decrease in number. And, high melting point intermetallic compounds Al2Ca and Al4Ca are formed. Meanwhile, the β-Mg17Al12phase become more dispersed. After 1.0wt.% Ca addition, the mechanical properties of the alloy at room and elevated temperature are improved.
