Role of grain orientation in the failure of Sn-based solder joints under thermomechanical fatigueJing HAN, Hongtao CHEN and Mingyu LI ( State Key Laboratory of Advanced Welding Production Technology... due to the bodycentered tetragonal (BCT) lattice structure of β-Sn. Grain orientations can significantly influence the failure mode of Pb-free solder joints under thermomechanical fatigue (TMF) due......
The Change of Orientation Relationships Between Austenite and α’-Martensite During Deformation in High Manganese TRIP SteelHai-Yan Yang,Jing Li,Ping YangSchool of Materials Science and Engineering,University of Science and Technology Beijing摘 要:In situ observation of electron backscattering diffraction technique was used to evaluate the orientation......
Article ID: 1003-6326(2005)02-0353-05 Induced effects of Cu underlayer on (111) orientation of Fe50Mn50 thin films WANG Lei(王 蕾), WANG Feng-ping(王凤平), LIU Huan-ping(刘还平), WU Ping(吴 平... (EDX) and Auger electron spectroscopy(AES) were used to analyze the compositional distribution. It is found that Cu underlayer has an obvious induce effect on (111) orientation of Fe50Mn50 thin films......
