The present work explored effects of laser surface melting on microstructure and topography evolution in AZ31B magnesium alloy. Thermokinetic experienced by the material during were simulated using a multiphysics finite element model. Microstructure phase examined scanning electron microscopy, X-ray diffraction, back scatter diffraction. Surface was evaluated white light interferometry. interac...

Abstract This study presents an investigation of the plunge stage in joining AZ31B magnesium alloy with friction stir welding using two different 3D finite element models based on Arbitrary Lagrangian–Eulerian formulation and Coupled Eulerian–Lagrangian formulation. The investigations are made ABAQUS program. Johnson–Cook plastic material law Coulomb used both models. Models compared terms temp...
