On the thermomechanical aging of LPBF alloy 718
Materials Science and Engineering: A, 2022 Heat treatment of products post additive manufacture are considered hugely important since the metallurgical condition post process is suboptimal. In the case of nickel-based superalloys, grain size, precipitate distribution and precipitate size are distinct from wrought equivalents. Appropriate heat treatment is required to ensure material performance.

Lamellar Spacing Modelling for LPBF Aluminum Parts
Journal of Manufacturing and Materials Processing, 2022 The high cooling rates reached during metal additive manufacturing (MAM) generate microstructures very different from those obtained by other conventional manufacturing methods. Therefore, research about the modeling of this type of microstructure is of great interest to the MAM community.
