Unlike conventional alloys, where carbon content typically promotes carbide compound formation and reduces localized corrosion resistance, the impact of in additively manufactured materials remains largely unexplored due to rapid cooling rates inhibiting formation. This study addresses novel question whether reducing benefits performance its underlying mechanisms Ni-Fe-Cr-based alloy 718. Employing high-resolution techniques microcapillary electrochemical methods, it was revealed that higher...
The auxetic cellular structures with two different chiral geometries (tetrachiral and hexachiral) were fabricated using laser powder bed fusion (LPBF) technology from materials (aluminium alloy AlSi10Mg stainless steel AISI 316L). specimen's microstructure, porosity surface texture observed by X-ray diffraction, optical electron microscopy micro-computed tomography. mechanical properties of all specimens determined experimentally a simple tensile test. results show that hexachiral...
Recently, Additive Manufacturing (AM) of metal components has opened new frontiers in heat transfer applications, going beyond the capabilities conventional technologies. Despite great design freedom offered by AM, when dealing with metals, there are a few issues that should be considered to exploit this manufacturing technology. In fact, surface roughness is expected affect performance devices, which can remarkably different from ones simulated computer codes. This paper presents critical...
Abstract Niobium (Nb) is a transition metal commonly used as an alloying element for increasing strength, toughness, corrosion resistance, and other properties of steel superalloys. Pure Nb, however, very interesting its excellent superconductivity. This makes it suitable producing superconducting magnets devices particle acceleration systems physics research (e.g., resonant cavities). In this work, the production Nb by Laser-Based Powder Bed Fusion (PBF-LB/M, also known Laser or LPBF)...
