Finite element analysis of rolling process for variable cross-section bladeKONG Xiang-wei(孔祥伟), LI Jia(李佳), LI Bin(礼宾) (School of Mechanical Engineering & Automation, Northeastern University... theory is no longer valid. The complexity and diversity of the blade cross-section determine it impossible to establish an universal theoretical model for the rolling process. Finite element analysis......
Finite Element Analysis of Push-Out Test of SiC Fiber Reinforced Titanium Matrix Composites () 摘要:Based on the interphase layer model and the spring layer model, an improved interface model... MPa. In addition, in order to better understand the interfacial properties of composites, some push out phenomenon were analyzed. 关键词:Titanium matrix composites; finite element method; interface......

Effects of trace element and purification on properties of AZ80 magnesium alloy LI Ying-ju(李应举), LUO Tian-jiao(罗天骄), YANG Yuan-sheng(杨院生) Institute of Metal Research, Chinese Academy of Sciences, Shenyang 110016, China Received 23 September 2009; accepted 30 January 2010 Abstract: The effects of trace element Fe on the corrosion behavior of AZ80 magnesium alloy were......
no element Ta are obviously decreased with the increasing of temperature. The main reason for the better creep resistance of the alloy, containing more elements Ta and Al, during steady creep is that it keeps a high volume fraction of γ′ phase. Keyword: single crystal nickel base superalloys; alloying elements; creep resistance; dislocation climb......
