Laser powder bed fusion (LPBF) processing of aluminum matrix composites (AMC) with blends AlSi10Mg and nanodiamond graphene additives was investigated. AMC 0.5 wt% nanodiamonds addition prepared by mechanical mixing, while multi-layered electrochemical deposition. Initial powders for LPBF were thoroughly characterized optimal parameters found based on the relative density analysis optical microscopy. Processing windows both AMCs moved towards lower energy possibly due to increased total...
Low performance is considered one of the main drawbacks laser powder bed fusion (LPBF) technology. In present work, effect AlSi10Mg layer thickness on melting process was investigated to improve LPBF building rate. A high-fidelity simulation melt pool formation performed for different thicknesses using Kintech Simulation Software Additive Manufacturing (KiSSAM, version cd8e01d) developed by authors. The after recoating operation obtained discrete element method. energy deposition particles...
Rare-earth (R)-iron alloys are a backbone of permanent magnets. Recent increase in price rare earths has pushed the industry to seek ways reduce R-content hard magnetic materials. For this reason strong magnets with ThMn
Volumetric cubic and cylindrical samples from MQP-S Nd-Fe-B-type material were 3D-printed using the LPBF technique. Two different scanning strategies used: convenient single laser exposure strategy newly proposed double aimed at improving melting process increasing density of synthesized material. Samples with a relative value higher than 95% obtained new by reducing void volume cracks. This was achieved decreasing internal stresses tendency to form propagate The half power followed full...
The crystal-field and exchange parameters are determined for the single-crystalline hydride $\mathrm{ErF}{\mathrm{e}}_{11}\mathrm{TiH}$ compound by analyzing experimental magnetization curves obtained in magnetic fields of up to 60 T. By using calculated we succeeded modeling theoretical 200 \cyrchar\CYRT{} study detail transition from ferrimagnetic a ferromagnetic state applied field.
In recent years, significant effort was made to make the 3D printing of fully dense rare-earth permanent magnets a reality. Since suitable Nd2Fe14B-based initial powder material became available, additive manufacturing implementation spread widely, which led many studies being focused on using this in printing. This study shows principal possibilities synthesis Nd-Fe-B by means laser bed fusion technique; moreover, progress increasing their magnetic properties. possible different approaches,...
Laser Powder Bed Fusion (LPBF) technology is a new trend in manufacturing complex geometric structures from metals. This allows producing topologically optimized parts for aerospace, medical and industrial sectors where high performance-to-weight ratio required. Commonly the feature size such applications higher than 300-400 microns. However, several possible of LPBF technology, example, microfluidic devices, stents coronary vessels, porous filters, dentistry, etc., significant increase...
The study is devoted to X-ray fluorescence spectroscopy (XRF) features of micro- and nanosized powder mixtures copper nickel. XRF a high accuracy method that allows for both qualitative quantitative analysis. However, the measurement error due size studied particles not usually taken into account, which limits use in some cases, such as analysis Ni-Cu coatings. In this paper, obtaining nickel nanoparticles was investigated, compositions considered detail. initial were detail using SEM, TEM,...
Details and features of the grain structure near interface region between AlN ceramic phase AlSi10Mg matrix after laser powder bed fusion (LPBF) were investigated. Aluminum nitride particles obtained through self-propagating high-temperature synthesis mechanically mixed with aluminum powder.
