Abstract

The effects of different rotational driving modes, using round and square rods, on the microstructure and mechanical properties of a deposition fabricated via additive friction stir deposition (AFSD) were investigated. A process monitoring kit was employed in this study to enable in-situ monitoring of real-time temperature, force, and torque of the contact interface and upsetting. The results show that the detected force and torque were reduced when a round rod was used as the feedstock. Furthermore, the corresponding microstructure was more refined, and the tensile properties in both the longitudinal and building directions improved, with a yield strength of 175 and 108 MPa, ultimate tensile strength of 188 and 129 MPa, and elongations of 30 and 33 %, respectively. These findings enhance deposition performance and optimize tooling structures in AFSD and other additive manufacturing technologies.

AA6061加性搅拌摩擦沉积过程中温度、力和扭矩的原位监测：旋转驱动方式的影响

研究了圆棒和方棒两种不同的旋转驱动方式对添加剂搅拌摩擦沉积（AFSD）沉积层微观结构和力学性能的影响。本研究采用过程监测套件，对接触界面和镦粗的温度、力、扭矩进行现场实时监测。结果表明，采用圆杆作为给料时，测得的力和扭矩都有所降低。相对应的组织更加细化，纵向和建筑方向的拉伸性能得到改善，屈服强度分别为175和108 MPa，极限抗拉强度为188和129 MPa，延伸率分别为30%和33%。这些发现提高了AFSD和其他增材制造技术的沉积性能并优化了工具结构。

期刊介绍： Materials Characterization features original articles and state-of-the-art reviews on theoretical and practical aspects of the structure and behaviour of materials. The Journal focuses on all characterization techniques, including all forms of microscopy (light, electron, acoustic, etc.,) and analysis (especially microanalysis and surface analytical techniques). Developments in both this wide range of techniques and their application to the quantification of the microstructure of materials are essential facets of the Journal. The Journal provides the Materials Scientist/Engineer with up-to-date information on many types of materials with an underlying theme of explaining the behavior of materials using novel approaches. Materials covered by the journal include: Metals & Alloys Ceramics Nanomaterials Biomedical materials Optical materials Composites Natural Materials.
