; 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... 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......
An Innovative Approach for Identifying Concrete Creep Degree Parameters based on Simulated Annealing Algorithm胡琼School of Civil Engineering,Harbin Institute of Technology摘 要:This paper proposes an approach to identify complex parameters describing concrete creep degree based on the simulated annealing (SA) principle.Through the existing engineering......
Temperature and Stress Dependence of Occurrence of Strain Burst in Cyclic Creep of AI-Mg Alloy朱世杰,阳志安,王中光摘 要:<正> Cyclic creep tests of Al-Mg alloy have beenconducted at a wide range of stress andtemperature.When Mg content is beyond 0.45%,the strain bursts can be observed in the cyclic creepcurves.There exists a critical stress for the occur-rence......
