摘      要：The ageing behavior of Mg-xAl-Zn alloys with a variation of AI contents （x=3,5,7,9 and 11 wt pct） were *** solution treatment and artificial ageing were carried out at 693 and 493 K,respectively. After the solid solution treatment,β-Mg-（17）Al-（12） was resolved to theα-Mg matrix in the specimens which contained Al up to 9 wt pct and partially resolved in the specimen of 11 wt pct *** ageing,theβ- Mg-（17）Al-（12） phase was precipitated at the grain boundary in the form of discontinuous precipitation and grown into the *** volume fraction ofβ-phase was increased with the Al *** strength increased with the volume fraction of precipitatedβ-phase,which was believed to strengthen the matrix.
