Abstract

Dissimilar friction stir welding (FSW) between 6101-T6 and 7075-T651 aluminium alloys was conducted. Three different parameters each were investigated for rotational speed and travel speed, and the effects of these parameters on the tensile behaviour, hardness and wear were evaluated. The results indicate that the ultimate tensile strength increases with an increase in the feed rate. However, the increase in rotational speed decreases the ultimate tensile values. The fractured analysis of the tensile samples shows similarities in the fractured pattern as all the samples failed at heat affected zone close to the 6101-T6 alloy. The hardness varies across the heat affected zones and nugget zone both at constant rotational speed and welding speeds. The highest resistance to wear occurred at 65 mm min−1 and 1850 rpm welding speed and rotational speed respectively while better material mixing was achieved at the nugget zone of the welds at 1250 rpm and 110 mm/min.

工艺参数对6101-T6和7075-T651铝合金搅拌摩擦焊接力学性能、材料流动和磨损性能的影响

对6101-T6铝合金与7075-T651铝合金进行了异种搅拌摩擦焊接。研究了三种不同的转速和行程速度参数，并评估了这些参数对拉伸性能、硬度和磨损的影响。结果表明，随着进给量的增加，合金的极限抗拉强度增大。然而，转速的增加降低了极限拉伸值。拉伸试样的断裂分析表明，试样的断裂模式相似，均在接近6101-T6合金的热影响区失效。在恒定转速和焊接速度下，在热影响区和熔核区硬度变化较大。焊接速度和转速分别为65 mm min - 1和1850 rpm时，合金的耐磨性最高;焊接速度为1250 rpm和110 mm/min时，熔核区材料混合效果较好。
