Abstract

This study investigates the impact of friction-stir welding (FSW) process parameters on the mechanical performance and fracture behavior of EN AW-2024-T3 aluminum alloy joints. A series of static and dynamic mechanical tests were conducted on six welded samples, revealing that the joint strength and fracture characteristics are highly sensitive to FSW parameters, particularly tool rotational rate, pin length, and traverse speed. Sample III, which exhibited the optimal combination of parameters, achieved the highest static load capacity, reaching 98.5% of the raw material's strength. Dynamic testing further confirmed Sample III's superior performance, with the highest recorded load capacity and significant energy absorption, as evidenced by ductile fracture features and high surface roughness. In contrast, Sample V, characterized by an excessive pin length, showed the lowest static and dynamic strength, along with a brittle fracture mode. The surface topography and SEM analysis of fracture surfaces indicated that optimized FSW conditions promote a ductile fracture mode, enhancing joint toughness under dynamic loading. These findings underscore the critical role of process parameter optimization in improving the mechanical properties and fracture resistance of FSW aluminum joints, making them more suitable for applications subjected to static and dynamic loading.

工艺参数对EN AW-2024-T3搅拌摩擦焊铝合金接头动、静载荷能力的影响

研究了搅拌摩擦焊（FSW）工艺参数对EN AW-2024-T3铝合金接头力学性能和断裂行为的影响。对6个焊接试样进行了一系列静态和动态力学试验，结果表明，接头强度和断裂特性对FSW参数非常敏感，尤其是刀具转速、销长和导线速度。样品III的静载能力最高，达到了原材料强度的98.5%，其参数组合最优。动态测试进一步证实了样品III的优越性能，其具有最高的承载能力和显著的能量吸收，这可以从韧性断裂特征和高表面粗糙度中看出。而试样V的静态强度和动强度最低，且断裂模式呈脆性断裂。断口表面形貌和SEM分析表明，优化后的FSW条件促进了韧性断裂模式，提高了接头在动载荷下的韧性。这些发现强调了工艺参数优化在提高FSW铝接头的力学性能和抗断裂性能方面的关键作用，使其更适合静态和动态载荷的应用。

期刊介绍： Archives of Civil and Mechanical Engineering (ACME) publishes both theoretical and experimental original research articles which explore or exploit new ideas and techniques in three main areas: structural engineering, mechanics of materials and materials science. The aim of the journal is to advance science related to structural engineering focusing on structures, machines and mechanical systems. The journal also promotes advancement in the area of mechanics of materials, by publishing most recent findings in elasticity, plasticity, rheology, fatigue and fracture mechanics. The third area the journal is concentrating on is materials science, with emphasis on metals, composites, etc., their structures and properties as well as methods of evaluation. In addition to research papers, the Editorial Board welcomes state-of-the-art reviews on specialized topics. All such articles have to be sent to the Editor-in-Chief before submission for pre-submission review process. Only articles approved by the Editor-in-Chief in pre-submission process can be submitted to the journal for further processing. Approval in pre-submission stage doesn''t guarantee acceptance for publication as all papers are subject to a regular referee procedure.
