Study on Mechanical Properties of 2024 Al Sheet Treated by SMAT

Abstract:

SMAT is applied as an innovation surface enhancement technology to introduce compressive stress in metallic materials. The strengthening effects of SMAT in mechanical properties were investigated on aluminium alloy. The yield strength obtained under tensile test had significant improvement which may achieve up to 440 MPa. In this paper, the experimental setup and results will be briefly described. Tensile properties measured before and after SMAT at ambient temperature. Results show that the highest strength that can be attained is 544 MPa by SMATed sheet of 1 mm thickness for 15 minutes and 518 MPa for the 2.5 mm one SMATed with 45 minutes, with the desirable ductility. The present study demonstrates this high strength and corrosion resistance aluminium alloy can be a potential candidate for applications in aviation industries.
