Effect of Threshold Stress on Anisotropic Creep Properties of Single Crystal Nickel-Base Superalloy SRR99Guoming Han,Jinjiang Yu,Xiaofeng Sun and Zhuangqi Hu Institute of Metal Research,Chinese Academy of Sciences,Shenyang 110016,China摘 要:The influence of orientation on the creep properties of the nickel-base single crystal superalloy SRR99......
temperatures due to the thermal stability of Ca-containing phases. At elevated temperatures, the creep resistance of ZA62 based alloys containing calcium is significantly higher than that of AZ91 which is the most commonly used magnesium alloy. Key words: magnesium alloys; ZA62 alloys calcium; creep properties ......
modulus decrease with the increase of the depth. In addition, the investigation of creep shows that the value of creep increases when the tensile strain ε＞10%. Key words: electrodeposited nickel coating; tension deformation; nano-indentation; creep 1 Introduction The nickel electrodeposited carbon steel sheet can be prepared by bilaterally electrodepositing nickel on low carbon steel sheet......
A 2-D mesoscopic model for the evaluation of creep damage induced by void growth in polycrystalline metalsKimiaki YOSHIDA摘 要:At elevated temperature,creep failures of polycrystalline metals after long-term constant loading are often caused by the nucleation,growth and coalescence of creep voids on the grain boundaries.Void fraction is an important......
