Powder-based additive manufacturing (AM) is revolutionizing the fabrication of advanced
engineering metallic materials, including aluminium (Al) alloys, which are the workhorse …

In this paper, the effect of Zr on the microstructure of laser additive manufactured Ti–6Al–4V
(TC4) alloy is studied by adding different contents of Zr (0%, 15%, 30%, 45%), and the …

Developing fine-grained high-strength titanium (Ti) alloys by additive manufacturing has
boomed interest for both research and application. The eutectoid element addition has been …

Coarse columnar grains and heterogeneously distributed phases commonly form in metallic
alloys produced by three-dimensional (3D) printing and are often considered undesirable …

Bimetallic wire arc additive manufacturing (AM) has traditionally been limited to depositions
characterized by single planar interfaces. This study demonstrates a more complex radial …

Microstructural defects and inhomogeneity of titanium alloys fabricated by laser powder bed
fusion (LPBF) make their fatigue behaviors much more complicated than the conventionally …

Laser powder bed fusion (LPBF) of high-strength Al alloys is challenging due to the
formation of both hot and cold cracks. In the present work, highly dense and crack-free …

In conventional duplex titanium (Ti) alloys, the soft primary α-precipitates (α p) are beneficial
to ductility with the loss of high yield strength, while the continuous α-precipitates at grain …

This review summarizes the recent research progress on the post-processing techniques to
improve the as-built metallic structure fabricated by additive manufacturing. The …
