Friction stir welding and friction stir processing of additively manufactured components: A comprehensive review
Source abstract
Abstract
Additive manufacturing (AM) has revolutionized the manufacturing of engineering parts with complex geometries. However, the expansion of industrial applications of this technology still faces challenges such as defects caused by the process, microstructural inhomogeneities, residual stresses, and dimensional limitations, which in many cases make the joining of several printed parts unavoidable. Meanwhile, friction stir welding (FSW) and friction stir processing (FSP) technologies have been proposed as efficient solid-state solutions to overcome these limitations. FSW enables the fabrication of high-strength and high-integrity joints in additively manufactured parts while avoiding the common problems of fusion welding processes, such as hot cracking, solidification defects, and thermal distortion. On the other hand, FSP, as an effective post-processing method, plays a significant role in removing porosity, refining microstructure, and improving mechanical properties. This review article comprehensively reviews recent advances in the application of FSW and FSP for additively manufactured materials. In this regard, the effects of friction stir technologies on the microstructural evolution and mechanical properties of major additive manufacturing alloy systems, including aluminum alloys, magnesium alloys, titanium alloys, steels, and nickel-based superalloys, have been systematically reviewed. The results of studies show that friction stir technologies significantly improve mechanical and functional properties by inducing dynamic recrystallization, porosity reduction, microstructure homogenization, and secondary phase modification. These enhancements can lead to increased strength, ductility, fatigue resistance, and corrosion resistance. In this respect, friction stir technologies represent a means to enhance the manufacturability, reliability, and structural performance of additively manufactured parts.
