This study investigates the fabrication of 316L stainless steel–WC metal matrix composites (MMCs) using a hybrid wire–powder Plasma Arc Directed Energy Deposition (DED) process. The system integrates an auxiliary powder feeder into a conventional wire-based plasma...

Fuel cells (FCs) represent a key technology for sustainable hydrogen-based energy systems, with proton exchange membrane fuel cells (PEMFCs) offering high efficiency and suitability for mobility and stationary applications. However, their performance and durability are strongly influenced by local inhomogeneities such as uneven humidification, temperature gradients, and transient flooding...

Laser Powder Bed Fusion (LPBF) of Ti-6Al-4V produces a characteristic non-equilibrium microstructure dominated by acicular α′ martensite due to high cooling rates inherent to the process. Recent studies have demonstrated the effect of build orientation on the thermal expansion of the as-printed Ti-6Al-4V. The observed expansion was partitioned into an isotropic reversible thermal strain and an...

Triply Periodic Minimal Surface (TPMS) structures have the potential to effectively tune the mechanical stiffness of orthopedic implants to mitigate stress shielding. To achieve the requisite low modulus, lattice wall thicknesses must approach the physical limits of Laser Powder Bed Fusion (L-PBF). While existing literature predominantly evaluates process parameters for walls thicker than 0.3...

Additive manufacturing is a transformative technology and manufacturing process that offers significant advantages over traditional manufacturing techniques, including greater design flexibility, higher material efficiency, reduced reliance on costly tooling, and shorter production lead times. Wire-based Direct Energy Deposition (w-DED) can produce large components on a scale of metres at high...

Laser Powder Bed Fusion (PBF-LB/M) enables the production of highly individualized and geometrically complex components, making it particularly attractive for tooling applications. However, the range of materials that can be processed without cracking remains limited, particularly in the case of tool steels. In this study, the addition of chromium carbides (Cr₃C₂) particles to the hot-work...

Refractory metals are attracting increasing interest for additive manufacturing applications in extreme thermal environments, owing to their high melting temperature, thermal stability and corrosion resistance. Among these, tantalum and Ta-W alloys are promising candidates for components operating under demanding thermal and chemical conditions.
This work investigates the LPBF processing and...

This study investigates the influence of thermal process conditions on the microstructural evolution and wear-related properties of a Fe-Cr-Nb coating produced by laser cladding. Iron-based hardfacing alloys with increased niobium content have attracted interest for wear-resistant applications due to their potential to form hard Nb-rich precipitates while maintaining good corrosion resistance....

The powder bed fusion of metals using an electron beam (PBF-EB/M) is an additive manufacturing (AM) technology that offers several advantages over conventional manufacturing methods, such as the possibility for integrated part designs or reduced scrap rates. Among the various AM technologies, PBF-EB/M with its high-power electron beam and its vacuum atmosphere provides a unique opportunity to...
