Mechanistic models for additive manufacturing of metallic components

H. L. Wei et al.

Summary: This article discusses the application of additive manufacturing (AM) in the manufacturing of metallic components, focusing on the factors that affect the microstructure, properties, and defects of components and the corresponding model predictions. The critical review of the application of transport phenomena models in AM studies is provided, and opportunities for future research are identified.

Metallurgy, mechanistic models and machine learning in metal printing

T. DebRoy et al.

Summary: Metal printing is widely used in key industries to produce complex parts that are difficult to manufacture conventionally, with metallurgy, mechanistic models, and machine learning driving its continued growth. Additive manufacturing allows for the printing of metallic parts with specific chemical compositions and properties, but the selection of alloys, printing processes, and variables results in a diverse range of microstructures, properties, and defects that impact the serviceability of printed parts.

Synchrotron diffraction characterization of dislocation density in additively manufactured IN 718 superalloy

Kartik Prasad et al.

Summary: In this study, 3D parts of Inconel 718 were fabricated using laser powder bed fusion, and the dislocation density was characterized. It was found that the dislocation density in AM IN 718 was very high and correlated well with the observed dislocation substructure using transmission electron microscope.

The effect of laser scanning strategies on the microstructure, texture and crystallography of grains exhibiting hot cracks in additively manufactured Hastelloy X

Kartik Prasad et al.

Summary: The study found that the grain size under the 45° scanning strategy is finer compared to the 90° scanning strategy, and the laser scanning speed is the main parameter affecting the variation in grain size. Energy density has a more dominant effect on hot cracking tendency compared to laser power.

In situ synchrotron diffraction study of a crack-free additively manufactured Ni base superalloy

Kartik Prasad et al.

Summary: The study revealed that the Ni base superalloy manufactured additively had a relatively higher dislocation density and a higher proportion of screw dislocations during plastic deformation compared to the wrought counterpart. Heat treatment is suggested for the as-built parts to improve efficiency.
