Effects of the crystallographic and spatial orientation of a lamellae on the anisotropic in-situ tensile behaviors of additive manufactured Ti-6Al-4V

Zheng Liu et al.

Summary: The study identified columnar grain morphology and typical alpha texture in the Ti-6Al-4V alloy fabricated using electron beam rapid manufacturing (EBRM), leading to significant anisotropic tensile behavior. The crystallographic texture of alpha phase and spatial orientation of alpha laths were found to be main factors inducing anisotropic tensile properties in the alloy.

Additive manufacturing of metallic lattice structures: Unconstrained design, accurate fabrication, fascinated performances, and challenges

Liang-Yu Chen et al.

Summary: Lattice structures, also known as architected cellular structures, have been widely used in various industrial sectors due to their excellent performance characteristics. Conventional manufacturing methods for lattice structures are often complex and limited, while additive manufacturing technology, based on computer-aided design models, offers a flexible and efficient platform for manufacturing complex components like lattice structures with minimal material waste. This overview highlights the potential of additive manufacturing in providing accurate fabrication for lattice structures with good quality by summarizing the state-of-the-art progress in metallic lattice structures manufacturing.

Digital materials design by thermal-fluid science for multi-metal additive manufacturing

Junji Shinjo et al.

Summary: Metal additive manufacturing shows great potential for designing advanced metallic parts of complex geometries, but the challenge lies in controlling the process dynamics such as melt flow, alloy mixing, and vapor mass loss. A high-fidelity thermal-solutal-fluid modeling approach has been developed to study the physical link between metal vapor mass loss and melt flow process, which is crucial for final quality. The digital materials approach is effective in understanding the complex thermal-fluid flow dynamics and can advance process-based materials design.

Non-layer-wise fracture and deformation mechanism in beta titanium cubic lattice structure manufactured by selective laser melting

Y. J. Liu et al.

Summary: This study achieved non-layer-wise fracture in a titanium alloy with 50% porosity cubic lattice structure manufactured by selective laser melting, mainly due to stress-induced progressive martensitic transformation and deformation twinning. The findings provide an alternative strategy of introducing non-layer-wise fracture in porous metallic materials through the coupled effect of phase transformation and twinning.

Spherical pores as 'microstructural informants': Understanding compositional, thermal, and mechanical gyrations in additively manufactured Ti-6Al-4V

Matthew J. Kenney et al.

Summary: This study investigates the characteristics and formation mechanisms of gas pores in additive manufacturing, specifically in Electron Beam Melted Ti-6Al-4V. The presence of large spherical pores exclusively in raster scan suggests perturbations caused by elastic instabilities from chemical and crystallographic variations. The findings provide insights into the physics of defects in the AM process.

Patcharapit Promoppatum et al.

Summary: This study investigated the sensitivity of material constitutive models on thermomechanical responses in laser powder bed fusion additive manufacturing of Ti-6Al-4V. The Johnson-Cook (JC) and Mechanical Threshold Stress (MTS) material plasticity models were compared, with MTS model providing more accurate estimation for cases involving changes in strain rate and temperature. The choice of material models was found to significantly impact the mechanical behavior prediction in LPBF process.

Implementation of Abaqus user subroutines and plugin for thermal analysis of powder-bed electron-beam-melting additive manufacturing process

Ning An et al.

Summary: Electron beam melting (EBM) is a metal powder bed fusion additive manufacturing (AM) technology widely used for creating three-dimensional objects. Recent versions of Abaqus offer a new plugin tool, AM Modeler, providing a user-friendly method for additive manufacturing process simulation. The study presents details of finite element implementation for thermal analysis of EBM process and provides source codes for future design and thermal analysis, promoting the use of AM Modeler plugin.
