“…Other methods have also been used for in situ monitoring of strain and stress development, such as fiber Bragg grating (FBG) sensors embedded in test specimen [262] and Barkhausen noise signal analysis. [263,264] In spite of the limited attempts, there still exist significant obstacles in applying in situ monitoring measures for RS control in AM. First, due to the fact that metal powder obscures most of the part except the top layer during powder bed AM, many noncontact metrology measurement techniques used for in situ distortion monitoring are impossible.…”

Powder bed fusion (PBF) and directed energy deposition (DED) are the two major types of metal additive manufacturing (AM) processes, in which significant residual stresses could be generated in the as‐deposited materials and in turn affect part quality and performance. Therefore, how to control and mitigate residual stress has been a most pressing challenge for metal AM. In this paper, we systematically review the significant efforts made in literature to address this challenge for both PBF and DED processes. The extensive survey covers the formation of residual stress in AM, influence of various AM process parameters, modeling techniques for predicting residual stresses, and post and in‐situ treatments for mitigating unfavorable residual stress distributions. More importantly, a critical analysis is provided to discuss the research gaps and opportunities, such that more exciting research will be stimulated to address the outstanding issues in this area, and improve the quality and service life of AM produced components. As a result, once being better equipped with residual stress control knowledge and tools, the industry will be more confident in adopting metal AM techniques.This article is protected by copyright.
