%(volume fraction) in Mg-12Li-Al alloy respectively. The results reveal that the creep resistance of the particulate composites is increased with increasing the content of MgO particulates and considerable improvement in creep resistance is observed in Mg-12Li-Al-MgO composites. However, over all range of temperatures and stresses, the creep data for these composites can be correlated using......
by sand casting. The creep curves of the experimental alloy were tested under different temperatures and stresses. The results show that the creep resistance of Mg-5.5Zn-2Gd-0.6Zr alloy is much higher...; 文献标志码:A Creep mechanism of Mg-5.5Zn-2Gd-0.6Zr cast alloy Zhang Sheng-li, Yang Guang-yu, Liu Shao-jun, Jie Wan-qi (State Key Laboratory of Solidification Processing, Northwestern......
