Microstructure evolution and mechanical behavior of Ni-based single crystal superalloy joint brazed with mixed powder at elevated temperatureGuanglei Wang1,2,Yuan Sun1,Xinguang Wang1,Jide Liu1,Jinlai...℃, and attentions were paid to the microstructure evolution during brazing and the stress-rupture behavior at 980℃ of such brazed joints after homogenization. Microstructure in the brazed joint generally......

FSSW joint of ZK60 Mg alloy and Q235 steel with a hot-dipped aluminum(Al)-containing zinc(Zn) coating was succes s fully realized.The detailed micro structural examinations proved that Al5 Fe2 phase... the interface between Al5 Fe2 and Mg,an orientation relationship of(622)Al5 Fe2//(3112)Mg and[158]Al5 Fe2//[2423]Mg was observed.The tensile-shear load of the ZK60-steel joint could reach 4.6......
of the applied normal stress and joint morphology to its shear strength are analyzed. According to the experimental results, the peak dilatancy angle of rock joint decreases with increasing normal stress, but increases with increasing roughness. The shear strength increases with the increasing normal stress and the roughness of rock joint. It is observed that the modes of failure of asperities......

correlation (DIC) was used to access the local strain fields in transversely loaded welds and to determine the local stress-strain curves of various regions in the joint. The results show that the DIC method... extrapolation, the complete local stress-strain curves were acquired and proved to be effective to predict the tensile behavior of the welded joint. During the tensile process, the fracture initiates from......
Effect of Ti-Al on microstructures and mechanical properties of plasma arc in-situ welded joint of SiCp/Al MMCs LEI Yu-cheng(雷玉成), ZHANG Zhen(张 振), NIE Jia-jun(聂加俊), CHEN Xi-zhang(陈希章) School... is improved, and stable molten pool is gained for the addition of the Ti-Al alloy. The mechanical properties of welded joint are effectively enhanced by the compact-grain structure and the new reinforced......
