  Investigation of microstructure and mechanical properties of multi-pass friction stir processing on precipitation hardened aluminum alloy

  By Vipin Sharma, Yogesh Dewang, Mohit Sharma, Yashpal Gupta

  Abstract: In the present study, multi-pass friction stir processing of aluminum AA2014-T651 alloy is per-formed with one and four passes. The multi-pass processing is performed at a tool rotational speed of 1000 rpm with a traverse speed of 63 mm/min. Microstructural characterization of fric-tion stir processed specimens indicated a significant grain refinement with equiaxed grains in the four pass specimen. Microhardness and tensile strength of the multi-pass specimen decreases with the …
