Abstract

In this study, a comparison between linear and zigzag patterned holes is carried out where the holes in the pattern are incorporated with tialite/aluminium titanate (Al2TiO5) particles at the weldment region during friction stir welding of AA6082-T6 aluminium alloy. Different values of tool rotational speed (TRS: 1000, 1200 and 1400 rpm) and welding speed (WS: 35, 40 and 45 mm/min) are considered for the fabrication of joints by both patterns. Visually, no defects are found in all the welded samples. Microstructural analysis has proven that the uniform distribution of particles along the weld region can be obtained by using a zigzag pattern. Maximum hardness is found in the stir zone (SZ), whereas minimum hardness is found in the heat-affected zone (HAZ) for all the samples. The maximum ultimate tensile strength (UTS: 268 MPa), maximum yield strength (YS: 200 MPa) and relatively higher elongation (EL: 7.89%) are exhibited by the Z5 sample, whereas minimum UTS (206 MPa) and minimum YS (142 MPa) was exhibited by L3 and Z7 samples, respectively.

在 AA6082 合金的 FSW 过程中，对用泰利特颗粒加固的线形孔和人字形孔的机械性能进行比较研究

在本研究中，对线形和人字形图案孔进行了比较，在 AA6082-T6 铝合金的搅拌摩擦焊接过程中，在图案孔中的焊接区域加入了钛酸铝（Al2TiO5）颗粒。在使用这两种图案焊接时，考虑了不同的工具转速（TRS：1000、1200 和 1400 rpm）和焊接速度（WS：35、40 和 45 mm/min）。从外观上看，所有焊接样品均未发现缺陷。微观结构分析表明，采用人字形模式可以获得沿焊接区域均匀分布的颗粒。所有样品的最大硬度都出现在搅拌区（SZ），而最小硬度则出现在热影响区（HAZ）。Z5 样品显示出最大极限拉伸强度（UTS：268 兆帕）、最大屈服强度（YS：200 兆帕）和相对较高的伸长率（EL：7.89%），而 L3 和 Z7 样品分别显示出最小极限拉伸强度（206 兆帕）和最小屈服强度（142 兆帕）。
