Abstract

Abstract Friction stir welding is a promising method for joining dissimilar metals. The transportation industries are increasingly focussing on enhancing the fuel efficiency of vehicles because of environmental regulations and costs. A solution to this problem can be manufacturing structures having the combination of both high-strength steel alloy as well as lightweight aluminium alloy. Researchers have been drawn towards solid-state joining techniques like friction stir welding (FSW) because of the challenges encountered in fusing steel and aluminium through traditional fusion welding methods. Unlike fusion welding, FSW does not involve the melting of parent materials. This review paper has made an effort to provide a comprehensive overview of the current research and development in the field of dissimilar FSW steel-Aluminium systems. The paper highlights the influence of Tool material and designs and also the influence of process parameters on weld quality. Moreover, the paper investigates the microstructural characteristics, Intermetallic compounds, mechanical properties, and common defects of dissimilar FSW joints, focusing on factors influencing joint strength and hardness. Furthermore, the environmental sustainability aspects of dissimilar have been discussed. Finally, existing variants and potential research areas are identified to enhance improved mechanical properties and process efficiency.

铝与钢异种金属系统的搅拌摩擦焊 (FSW) 工艺综述

摘要搅拌摩擦焊是一种很有前途的异种金属连接方法。由于环保法规和成本的原因，运输业越来越重视提高车辆的燃油效率。解决这一问题的方法是制造既有高强度钢合金又有轻质铝合金的结构。由于传统的熔焊方法在融合钢材和铝材时遇到困难，研究人员被搅拌摩擦焊（FSW）等固态连接技术所吸引。与熔焊不同，FSW 不涉及母体材料的熔化。本综述文件旨在全面概述目前在异种 FSW 钢铝系统领域的研究和发展情况。论文强调了工具材料和设计的影响，以及工艺参数对焊接质量的影响。此外，论文还研究了异种 FSW 接头的微观结构特征、金属间化合物、机械性能和常见缺陷，重点关注影响接头强度和硬度的因素。此外，还讨论了异种材料的环境可持续性问题。最后，确定了现有的变体和潜在的研究领域，以提高机械性能和工艺效率。
