متن کاملDuctility Improvement of an AZ61 Magnesium Alloy through Two-Pass Submerged Friction Stir Processing
Friction stir processing (FSP) has been considered as a novel technique to refine the grain size and homogenize the microstructure of metallic materials. In this study, two-pass FSP was conducted under water to enhance the cooling rate during processing, and an AZ61 magnesium alloy with fine-grained and homogeneous microstructure was prepared through this method. Compared to the as-cast materia...
متن کاملSimulation of Peak Temperature & Flow Stresses during Friction Stir Welding of AA7050-T7451 Aluminium Alloy Using Hyperworks
To overcome limitations of fusion welding of the AA7050-T7451aluminum alloy friction stir welding (FSW) has become a prominent process which uses a non-consumable FSW tool to weld the two abutting plates of the workpiece. The FSW produces a joint with advantages of high joint strength, lower distortion and absence of metallurgical defects. Process parameters such as tool rotational speed, tool ...
متن کاملLiquation and re-solidification in thermo-mechanically affected zone during friction stir spot welding of AZ91 alloy
The present research aims to study the liquation and re-solidification of liquid during friction stir spot welding of AZ91 alloy. Although friction stir spot welding is a solid-state process, the presence of Mg17Al12 intermetallic compounds results in liquation during the welding process. In this study, friction stir spot welding was performed with a tool rotational speed of 2500 rev/min and a ...
