Special Issue Information

Dear Colleagues,

We are pleased to invite you to contribute to a Special Issue titled “Additive Manufacturing and Processing of Metallic Alloys and Composites,” in collaboration with Metals, an open access journal published by MDPI. Additive manufacturing (AM) continues to revolutionize the way we design, manufacture, and process metallic alloys and composite materials, opening new possibilities in industries such as the aerospace, automotive, biomedical, and energy sectors. This Special Issue seeks to bring together cutting-edge research and developments in this exciting area.

Scope of this Special Issue: This Special Issue aims to provide a comprehensive overview of the latest advancements and breakthroughs in the field of additive manufacturing and processing of metallic alloys and composites. We encourage contributions that address fundamental challenges, innovative solutions, and emerging trends that have the potential to significantly impact the way metallic materials are designed and processed via AM technologies.

Topics of interest include but are not limited to the following:

  1. Additive manufacturing techniques: innovations in LPBF, DED, binder jetting, cold spray, EBM, and WAAM.
  2. Materials for additive manufacturing: design and processing of metallic alloys (e.g., titanium, steels, superalloys), composites, and multi-material AM.
  3. Processing–structure–property relationships: microstructural evolution, mechanical properties, residual stress, and defect mitigation in AM parts.
  4. Computational modeling and simulation: modeling thermomechanical behavior, microstructure evolution, and multi-physics simulations of AM materials.

Researchers and practitioners are invited to submit original research articles, comprehensive review articles, and short communications that contribute to the broad field of additive manufacturing and metallic/composite processing. Each submission will undergo a peer-review process to ensure the quality and impact.

The performance of the selective electron beam melting (SEBM) products depends on the SEBM-induced temperature and stress. Here, the thermomechanical finite element simulations are conducted to investigate the dynamic evolution of temperature and the thermal stress of melt pool during the SEBM process of Ti6Al4V alloys under various processing parameters and scanning strategies. The results show that the melt pool undergoes three stages of preheating, melting, and remelting under the influence of adjacent scanning tracks. This complex thermal history drives significant changes in thermal stress within the melt pool. After adjusting the processing parameters, it is found that a low scanning speed and high electron beam energy result in a high temperature gradient and stress in the molten pool. Compared to the electron beam energy, the scanning speed has a more significant impact on temperature and residual stress. For the dual-electron-beam scanning strategy, the coupling thermal effect between electron beams can reduce the temperature gradient of the melt pool, thereby suppressing the formation of columnar crystals. The electron beam energy of 300 W and the scanning speed of 1.5 m/s can be selected under various scanning strategies, which are expected to suppress the formation of coarse and columnar β grains and achieve relatively low residual stress. These results contribute to providing a theoretical basis for selecting optimized process parameters and scanning strategies. Full article
