氧化膜对6005A-T6铝合金双轴肩搅拌摩擦焊接头性能的影响
摘要
通过拉伸试验、弯曲试验和金相组织分析
研究氧化膜对6005A-T6铝合金双轴肩搅拌摩擦焊接头性能的影响。在不进行表面氧化膜处理的情况下
接头中会产生"C"形S线
接头抗拉强度184.3 MPa
为母材强度的72.2%
弯曲不合格;在进行表面氧化膜处理的情况下
接头中不存在明显的S线
接头分为焊核区(WNZ)、热机影响区(TMAZ)、热影响区(HAZ)和母材(BM)
接头抗拉强度219.3 MPa
为母材强度的86%
弯曲合格。
Abstract
This paper studies the influence of oxide film on the performance of 6005 A-T6 aluminum alloy BT-FSW joints through the analysis of tensile test
bending test and microstructure. Without removing off oxidation film
the joint produces the C-shaped S line.The tensile strength of the joint is 184.3 MPa
72.2% of the strength of the parent material. The bending of the joint is not qualified.With removing off oxidation film
the joint does not show an obvious S line. The joint is divided into WNZ
TMAZ
HAZ and BM. The tensile strength of the joint is 219.3 MPa
86% of the strength of the parent material. The bending of the joint is qualified.
