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 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 show that the
max. 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 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 supported results due to dynamic recrystallization.
