Characteristics Of FSW And UWFSW Joints Of AA2519-T87

Apr 01, 2021  The FSW joint fabricated using tool rotation speed of 1400 rpm exhibit lowest hardness of 78 HV whereas the joint fabricated using same tool rotation speed under water cooling exhibit hardness value of 88 HV. It is observed that the UWFSW joints exhibit higher hardness than the FSW joints in

Top Surface Microstructure Of Friction-stir Welded AA2524

Mar 01, 2012  The metallographic microstructures on the surface of the FSW joints are shown in Fig. 1.The weld joint was divided along the traverse direction into four distinct regions: the NZ, HAZ, TMAZ, and base material (BM), as shown in Fig. 1a. In the as-polished surface of the NZ under the shoulder of the FSW tool, the “onion rings” featured in the cross-section stir zone were replaced by the

A Review Of Friction Stir Welding Of Aluminium Matrix

Dec 05, 2021  This review aims to outline the current state-of-the-art of joining AMCs by FSW with a number of specific issues discussed including the FSW process, the application of MMCs, weldability of aluminium and AMC materials, macro and microstructure, mechanical properties of FSW
