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...
Abstract Results of DTA‐TG investigation and chemical analysis electro‐exploded aluminum nanopowders, passivated and/or coated with the non‐inert reagents: nitrocellulose (NC), oleic acid (C 17 H 33 COOH) stearic 35 COOH), which were suspended in kerosene ethanol, amorphous boron, nickel, fluoropolymer, ethanol air (for comparison), are discussed. Surface protection nanopowders by coatings different origin results significant advantages energetic properties powders. Aluminum a protecting...
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...
Abstract Nanoaluminum powder (nAl, nominal size of particles 50 nm and 100 nm), obtained by electrical explosion wires, was passivated air coated several different protective organic reagents to assess the effects on ballistics nAl-loaded hydroxyl-terminated polybutadiene (HTPB)-based solid fuel with respect pure HTPB baseline. The nAl samples were characterized transmission electron microscopy (TEM), Brunauer–Emmett–Teller (BET), chemical analysis active aluminum content (Al°) added...
Abstract For testing the determination of reactivity aluminum powders it is proposed to use following parameters: temperature beginning oxidation, maximal oxidation rate, degree transformation (degree oxidation) aluminum, relative thermal effect. Parameters for an evaluation were chosen analysis results a non‐isothermal different grain size under conditions programmed heating (the oxidizer being air). According method testing, sample ultrafine powder UFAP‐4 produced by electrical explosion...
Non-isothermal oxidation of brown coal with 5 wt% Cu(NO3)2, Ce(NO3)3 and {2.5 Cu(NO3)2 + 2.5 Ce(NO3)3} additives was studied. The introduction carried out by an incipient wet impregnation method to ensure uniform distribution cerium copper nitrates within the structure powdery samples (according SEM EDX mapping). reactivity studied in isothermal regime at 200 °C (1 h) DSC/TGA °C/min heating rate. implementation found reduce significantly onset temperature (ΔTi = 20–55 °C), delay time (Δti...
A method of alumina production based on hydrochloric acid processing kaolin clays from the East Siberian deposits was studied. Hydrochloric leaching carried out at 160 °C. The solution subjected to a two-stage crystallization aluminum chloride hexahydrate (ACH). precipitated crystals were calcinated in air temperature above 800 °C produce alumina. main part water and chlorine during thermal decomposition ACH removed 400 influence duration calcination residual content optimal 900 with 90 min....
Methane pyrolysis is one of the possible methods to produce low-carbon hydrogen. One most promising catalysts for methane Fe due its availability, relatively low cost and high working temperature. In presented paper, on unsupported (without a carrier) sponge iron in form powder was studied temperature range 700–1100 °C. carried out stainless-steel tube reactor with an inner diameter 10 mm. The heated locally by propane burner, length zone about 8 cm along tube. feed rates were 50, 100, 200...
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...
Abstract The paper investigated the effect of metal nanopowders additive on combustion properties HMX/CL‐20/AP/polyvinyltetrazole binder/Al propellants. Using thermal analysis, authors described aluminum, boron, zinc, nickel, copper, and molybdenum identified in a pressure range from 4 to 10 MPa with step 1 MPa. No significant correlation between oxidation n‐Me powders propellants was discovered. An addition caused an increase propellant burning rate by approximately 30 % for n‐Al, n‐B,...
