The factors that have an impact upon fatigue strength are residual stress, stress concentration, the mechanical properties of the material, and the macrostructure and microstructure. Residual stress is one of the most important factors but its effect on high-cycle fatigue is of more concern than the other factors. Residual stress is a tension or compression that exists in a material without any...

Residual stresses induced by the welding processes may, in some cases, result significant warping and distortions that can endanger integrity of welded structures. This document reports an investigation process to make a dissimilar T-joint through advanced Finite Element (FE) modelling dedicated laboratory test. The consisted two plates materials, AISI304 S275JR steels, both having thickness 5 ...

In this work, the dissimilar joint of AA7003-T4 and 6060-T4 alloy has been produced by friction stir welding (FSW). The microstructure was examined by optical microscope (OM), electron back scattered diffraction (EBSD), transmission electron microscopy (TEM), and the mechanical properties of the joint were investigated. It is demonstrated that sound dissimilar joint can be produced through FSW....

Despite its exceptional ability to join dissimilar materials and environmental friendliness, several challenges must be addressed in magnetic pulse welding (MPW). The conventional weldability criterion (i.e., minimum impact velocity) is analytically calculated as a function of material properties without considering the geometry electromagnetic coil, electrical physical parameters, making veloc...
