Progress in Additive Manufacturing

Metastable β-titanium alloys are attractive for their high strength-to-density ratio, good hardenability, excellent fatigue behavior, and corrosion resistance. Among these alloys, β-21S, with a composition of Ti–15Mo–3Nb–3Al–0.2Si (wt%), is known …

The final part density in laser powder bed fusion is influenced by the powder particle size distribution. Too fine powders are not spreadable, and too coarse powders cause porosity. Powder blends, especially bimodal ones, can exhibit higher …

The process of friction stir welding (FSW) can be applied not only to the conventional sense of materials joining, but also as a method of solid-state processing and additive manufacturing with the use of lap joints. Two stacked lap weld builds …

Metal additive manufacturing (AM) has been recently acknowledged as a method to produce metal parts with complex geometries and unique characteristics. In general, metal AM components are used in applications where enhanced mechanical properties …

This paper presents an investigation on the electrochemical corrosion behaviour of Laser Directed Energy Deposition (LDED)-based additive manufacturing built Inconel 718 (IN718) for the first time in various acidic environments (2 M HNO3, 2 M HCl …
