In powder bed fusion additive manufacturing, the feedstock quality is of paramount importance; as process relies on thin layers being spread and selectively melted to manufacture 3D metallic components. Conventional assessments for manufacturing are limited particle morphology, size distribution, apparent density flowability. However, recent studies highlighting that these techniques may not be most appropriate. The problem exacerbated when studying aluminium powders their complex cohesive...
Wire feeding can be combined with different heat sources, for example, arc, laser, and electron beam, to enable additive manufacturing repair of metallic materials. In the case titanium alloys, vacuum operational environment beam systems prevents atmospheric contamination during high-temperature processing ensures high performance reliability additively manufactured or repaired components. present work, feasibility developing a process that emulates refurbishing an “extensively eroded” fan...
Selective laser melting (SLM) is an attractive manufacturing technique for the production of metal parts with complex geometries and high performance. This process characterized by highly localized energy inputs during short interaction times which significantly affect densification process. In this present work, experimental investigation fabricating 316L stainless steel SLM was conducted to determine effect different densities on behavior resultant microstructural development. It found...
A method was developed to suppress the crack formation during laser powder bed fusion (LPBF) of molybdenum (Mo). The uses a nitrogen (N2) atmosphere fabricate crack-free samples without any additional processing. To compare with effect N2 atmosphere, were prepared under an argon (Ar) as well same process parameters. microstructure analyses by optical and high-resolution electron microscopy revealed that produced this condition, whereas grain boundary cracks observed throughout sample...
