Investigation the Mechanical Properties of 2024AA of Friction Stir Processing

Abstract

The 2024AA has good mechanical properties and used for many application, there was many research in the field of friction stir welding in past 20 years age, now many research focusing in the friction stir processing technology which has many advantage according to the mechanical properties investigation, in this paper comparing the 2024AA base metal with friction stir process 2024AA with different feed rate and rotation speed, the feed rate that has been used is (20, 35, 50 mm/min), although in the rotation speed (1400, 2000 rpm) where used. The mechanical properties has been investigate, the hardness has been tested in different location. The tensile strength in 2024AA has been found 460 MPa, as comparing with 35, 1400 friction stir processing the ultimate tensile stress found to be 420 MPa so that percentage of improving 9.5 %. The flexural stress in 2024AA has been found 828 MPa as comparing with 35, 1400 friction stir processing the flexural stress found to be 745 MPa so that percentage of improving 11.1 %.
