APPLICATION OF FSW TECHNIQUE TO AA2124/%25SiCp-T4 ALUMINUM MATRIX COMPOSITES

Journal Title: The International Journal of Materials and Engineering Technology - Year 2019, Vol 2, Issue 1

Abstract

In the present study, AA2124/25%vol.SiCp-T4 aluminum metal matrix composite plates were successfully friction stir butt joined using various welding parameters. The influence of the welding parameters on the temperature distribution, micro-hardness and tensile strength of the joints was investigated and the joint efficiency was determined. The temperature measurements were obtained from four points at the each side of the weld, namely tool advancing and tool retreating side, from the 15 mm away from the weld center. Based on these measurements, the average peak temperature in the weld nugget was predicted according to studies in literature. As a result of the study, the temperature dissipation shows that the maximum 180-270 °C occurred at 15 mm away from the centerline of the weld. The maximum and minimum values of joint performance was obtained at 1400/40 and 1400/100 rpm/min welding parameters as 73% and 59.32%, respectively. It was not detected a noticeable differences in micro-hardness measurements of the stir zone. It is determined that micro-hardness distribution in stir zone is in accordance with literature results which can be attributed to dynamic recrystallization.
