Effect of Si, Ca and Sr on the Creep-Resistance of AZ91D Alloy


Article Preview

In present work, Sr, Ca and Si elements were added into AZ91D and cast into a metallic mold. The influence of these elements on AZ91D magnesium alloy were studied systematically with the purpose of developing a new magnesium alloy with good mechanical properties at both room and high (150°C~200°C) temperature. Additionally, a simple method to qualitatively analyze the high-temperature creep performances of magnesium alloys was designed and implemented.
