摘要/Abstract

摘要： 铝合金拼焊成形技术兼具有材料和结构双重轻量化效果，在汽车轻量化发展趋势下，拥有巨大的应用前景。研究铝合金搅拌摩擦焊接头微观组织和力学性能，建立搅拌摩擦焊接头的有限元模型，试验结合力学计算研究搅拌摩擦焊接头的塑性变形规律。结果发现：铝合金搅拌摩擦焊接头具有明显的力学性能不均匀性，搅拌摩擦焊接头在拉伸过程中热影响区最先发生屈服和颈缩；焊后热处理和高温成形可以显著提高拼焊板的成形性和力学性能。2024铝合金搅拌摩擦焊拼焊板的最佳成形温度为450℃，固溶处理后接头未发现晶粒异常长大现象，热冲压时引入的变形与成形后的时效相结合，产生形变时效的强化效果，可获得高强度的汽车拼焊构件。

Abstract: The aluminum alloy tailor-welding forming technology has the dual lightweight effect of material and structure, and has great application prospects under the trend of automobile lightweight development. The microstructure and mechanical properties of friction stir welding joints of aluminum alloys are studied, a finite element model of friction stir welding joints is established, and the mechanical calculation with experiments to study the plastic deformation law of friction stir welding joints is combined. The results show that the aluminum alloy FSW joint has obvious uneven mechanical properties, and the heat affected zone of the FSW joint firstly yields and necks during tensile test; post-weld heat treatment and hot forming can significantly improve the formability and mechanical properties of tailor-welded plates. For AA2024 FSW tailor-welded blanks, 450 ℃ is the optimal forming temperature. AGG is not found in the joint after solution treatment. Combining the deformation during hot stamping with the aging after forming produces a strengthening effect of deformation aging, which can obtain high-strength automotive welded components.
