%. This was attributed to the defect free stir zone formation and grain size strengthening. Key words: friction stir welding; dissimilar joint; aluminium alloy; microstructure; tensile strength 1... AA5xxx and AA6xxx joints was investigated by HECTOR et al [16] and reported that FSW process can join dissimilar aluminium material of higher tensile strength. KHODIR and SHIBAYANAGI [17] investigated......
Fracture strength of centre surface cracked tensile specimens made of 2219-T87 Al alloy welding S. RAJAKUMAR1, T. CHRISTOPHER2 1. Thanthai Periyar Government Institute of Technology, Vellore-632002... were determined for the material. Fracture analysis was carried out considering the ultimate tensile strength value and the fracture data of aluminium base metal and weldment metal generated from......
, tensile strength increases with the increase of strain rate. The two original specimens show an obvious strain-softening behavior while the annealed specimen exhibits a much longer steady-state deformation...

that the incompletely recrystallized and stress-relieved specimens show the most desirable ductility and ultimate tensile strength, and that the recrystallization treatment promotes susceptibility to the test... (peak), and then tends to decrease with further increasing heat-treatment temperature (Fig.4(a)). The ultimate tensile strength basically decreases with increasing recrystallization degree.

. The bond strength of the interface was measured by the tensile tests and the morphology of the fracture surface was observed by SEM. The observation of the interface reveals that there are two distinct.... The tensile tests indicate that the distribution of strength in radial direction at the interface is inhomogeneous, and the central area of the interface performs greater bond strength than......
Corrosion behavior of 2195 and 1420 Al-Li alloys in neutral 3.5% NaCl solution under tensile stress LI Jin-feng(李劲风), CHEN Wen-jing(陈文敬), ZHAO Xu-shan(赵旭山), REN Wen-da(任文达) , ZHENG Zi-qiao(郑子樵...-Li alloys under 308 and 490 MPa tensile stress respectively in neutral 3.5% NaCl solution were investigated using electrochemical impedance spectroscopy(EIS) and scanning electron microscope(SEM......

The dynamic disturbance frequencies were set to 1, 10, 20, 30, 40, and 50 Hz. The results show that the tensile failure strength and peak displacement of red sandstone specimens under coupled......
on the investigation of the tensile properties of spray formed ultra-high strength Al10.8Zn2.9Mg1.9Cu alloys, the high-cycle fatigue properties under different theoretical stress concentration factors were investigated, the fatigue fracture surfaces and microstructures were observed, and the fatigue mechanism was discussed. The results indicate that the ultimate tensile strength of spray formed Al10.8Zn2.9Mg1.9Cu......
