Scientific basis for tungsten and tungsten alloys tailored for electron beam additive manufacturing
▶Summary
The ElectronsMatter MSCA Doctoral Network addresses critical challenges in the additive manufacturing (AM) of tungsten and tungsten alloys, a field crucial for advancing applications in energy, aerospace, and green technologies. Tungsten, with its exceptional properties such as the highest melting point of any metal and excellent resistance to wear and corrosion, is ideal for extreme environments. However, its high melting temperature and brittleness make it difficult to process using conventional methods, limiting its industrial use.This project leverages electron beam powder bed fusion (PBF-EB), an AM technology with unique capabilities for processing refractory materials like tungsten. By combining computational modeling, advanced characterization, process design, novel in-process monitoring methods, and mechanical behavior analysis, ElectronsMatter aims to develop optimized strategies for manufacturing dense, crack-free tungsten components with complex geometries. The network will tackle key challenges such as defect formation, microstructure evolution, and process monitoring, driving innovations in AM and materials design. Furthermore, material reusability will be studied, enhancing the sustainability of the process. ElectronsMatter integrates the expertise of leading academic and industrial partners to train a new generation of materials scientists. Doctoral Candidates will benefit from interdisciplinary research, industrial secondments, and cutting-edge training in sustainability, innovation, and advanced manufacturing. This aligns with the MSCA Work Programme by fostering skills for the green and digital transitions and strengthening Europe’s competitiveness in sustainable manufacturing technologies.By addressing the technical, environmental, and societal challenges in AM, ElectronsMatter will not only advance materials science but also prepare a future-ready workforce equipped to meet the demands of a rapidly evolving industrial landscape.
