structures induced by higher temperature and diffusion of solute atoms towards these larger or tangled dislocations, was proposed to explain the effect of temperature on microstructural evolution and creep... could grow to solute atmospheres pinned dislocations, which is thought mainly responsible for Stage II with a creep strain rate of zero. During Stage III with an increasing creep strain rate, solute......
Creep behavior of SnAgCu solders with rare earth Ce doping ZHANG Liang(张 亮)1, XUE Song-bai(薛松柏)1, GAO Li-li(皋利利)1, ZENG Guang(曾 广)1, CHEN Yan(陈 燕)2, YU Sheng-lin(禹胜林)1,3, SHENG Zhong(盛 重)1 1.... The tensile creep behavior of bulk SnAgCuCe solders was reported and compared with SnAgCu solders. It is found that SnAgCuCe solders show higher creep resistance than SnAgCu alloys. Moreover, Dorn model......
TENSILE STRENGTH AND CREEP RESISTANCE OF Mg-9Al-1ZnBASED ALLOYS WITH CALCIUM ADDITION Y.S.Sun1,W.M.Zhang1,X.G.Min1 (1.Department of Materials Science and Engineering, Southeast University, Nanjing... 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......

with varying stress exponents. In the region of high temperature and low strain rate, Mg-2Al alloy exhibits characteristics of solute-drag creep with n≈3.83 and an activation energy of 141.46 kJ/mol. Tensile..., and the effects of solute Al on the deformation mechanism were investigated. The Mg-2Al plate with an average grain size of 48.35 μm was made by smelting, casting, hot rolling and heat treatment. Under......
