A review on additive manufacturing of AA2024 and AA6061 alloys using powder bed fusion

Abstract

Additive manufacturing (AM) is a production facility for tailoring intricately shaped components. Unlike traditional machinery, ease of manufacturability along with intrinsic material saving nature makes AM gain eminence. This paper solely focuses on the capability of aluminium alloys, especially AA2024 and AA6061, being additively fabricated using the widely preferred AM technique of Powder Bed Fusion (PBF). The mechanism of PBF is elucidated by availing the experimental response mirrored in these alloy systems from erudite literary works. Additionally, a comparative review on yield strength, ultimate strength, elongation and hardness property values between wrought condition and PBF fused samples of these alloys has also been discussed. To the end, challenges involved in PBF built components were also addressed by the subsequent emphasis laid over improvement strategies.
