Abstract Wire Arc Additive Manufacturing (WAAM) is an emerging group of methods for
producing large parts with complex geometries and varying wall thicknesses. These parts …

During laser directed energy deposition (LDED), the complex microstructure created by
multiple rapid heating and cooling cycles results in the uneven performance of the parts …

The repeating nature of additive manufacturing (AM) translates into quasi-periodic repeating
hierarchical microstructures, which vary depending on the working principle of the AM …

Revealing underlying mechanisms of IN718 superalloy's negative strain rate sensitivity
behavior at elevated temperatures is significantly important for its further applications in …

The anisotropy of yield strength of additive manufactured (AM) Al-Mn-Sc alloy is attributed to
the diverse distribution characteristics of grain size, aspect ratio and orientation. This work …

Directed energy deposition (DED) describes the process of depositing molten metal in wire
or powder form with a focused energy beam source in a layer-by-layer fashion to create a …

The rate-and temperature-dependent mechanical behavior of unidirectional carbon fiber-
