210096, China) Abstract:Small amount of calcium addition to the Mg-9Al-0. 8Zn-0.2Mn(AZ91) alloy resulted in the obvious influence on mechanical properties. The yield strength of the alloys increased with the increase of Ca addition and maximum strength was obtained from the alloy containing 0.15% of Ca. The creep resistance at the temperatures between 150-200°C was also significantly increased......
