tailieunhanh - Friction stir welding process: An investigation of microstructure and mechanical properties of Al Alloy AlMg4.5Mn joint

Aluminium alloy has got comprehensive acceptance in the manufacturing of light weight frames, marine structures which require high strength and worthy corrosion revulsion. The present investigation work focuses on friction stir welding process in which influences of operating parameters have been studied on friction stir welded butt joints. | Friction stir welding process An investigation of microstructure and mechanical properties of Al Alloy joint Engineering Solid Mechanics 2017 145-154 Contents lists available at GrowingScience Engineering Solid Mechanics homepage esm Friction stir welding process An investigation of microstructure and mechanical properties of Al Alloy joint Jitender Kundua and Hari Singhb a Research Scholar Department of Mechanical Engineering National Institute of Technology Kurukshetra 136119 India b Professor Department of Mechanical Engineering National Institute of Technology Kurukshetra 136119 India A R T I C L EI N F O ABSTRACT Article history Aluminium alloy has got comprehensive acceptance in the manufacturing of light Received 6 October 2016 weight frames marine structures which require high strength and worthy corrosion revulsion. Accepted 3 February 2017 The present investigation work focuses on friction stir welding process in which influences of Available online operating parameters have been studied on friction stir welded butt joints. The FSWed joints 6 February 2017 Keywords specimens have been produced by experimentation at three levels of tool traverse speed and FSW tool rotational speed keeping input force and tool tilt angle constant. Mechanical properties AA5083 and microstructure of welded joints have been investigated in the present study. Change in the Micro-hardness microstructure at different zones which transforms the mechanical properties of welded joints Microstructure was due to the asymmetrical flow of material and thermal cycles around the pin. The second Ductility phase beta grains are formed as the very high temperature reached due to input parameters Tensile strength combinations. Traverse speed TS and tool rotational speed TRS are taken in a range of 16- 40 mm min and 500-1400 rpm respectively. The best combination of parameters results in higher tensile strength which is well supported by .
