Zusammenfassung: | The purpose of this study is to investigate the friction stir weld quality of pulverized glass waste (PGW)-reinforced AA6061-T6 and develop a model predicting the hardness of the joint. Friction stir welding of PGW-reinforced AA6061-T6 was done within a process window. The process was optimized for the maximum joint hardness. Thereafter, the result of the hardness was used to develop a model using a novel statistical analytical technique. The addition of PGW enhanced the AA6061-T6 friction stir welded joint hardness. The maximum hardness (112 HV) of the PGW-reinforced joint, which was obtained at optimal setting of 900 rpm rotational speed, 40 mm/min traverse speed and 1o tilt angle, is by a factor of 1.72 greater than the unreinforced joint and close to the hardness of the as-received AA6061-T6 (120 HV). The developed model can predict the hardness of the PGW-reinforced AA6061-T6 joint up to an accuracy of 89%. The model shows that the rotational speed, tilt angle and their interaction contributed significantly to the hardness of the PGW-reinforced AA6061-T6 friction stir welded joint. This model is suitable for determining the hardness property of particle-reinforced AA6061-T6 friction stir welded joint at varying processing parameters. |
