Abstract Fine and ultra‐fine powders are actively studied in pyrotechnics, explosives propellants. The important questions how to produce a powder with specified characteristics use the produced.
An experimental and theoretical investigation of the strength properties aluminum alloys strengthened by dispersed nanoparticles, as well determination significance various mechanisms responsible for strengthening material, was carried out. Results demonstrate that hardening alloy A356 Al2O3 ScF3 nanoparticles leads to an increase in yield strength, ultimate tensile plasticity. Despite similar size physicomechanical significantly affect possibility increasing mechanical alloy. A...
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...
The article considered the solution of inverse problem chemical kinetics analysis experimental data a thermogravimetric experiment at constant sample heating rate. fitting method for identifying parameters kinetic triplet using integral model solid-state reaction based on modified Arrhenius equation is described. effectiveness proposed approach was confirmed by solving test cases low, medium, and high rates material conversion. Unlike other methods, setting mechanism not required, as they...
This paper presents a comparative analysis of morphology, chemical and phase compositions, particle size distribution nanopowders produced by electric explosion wire (EEW) plasma-chemical methods. The possibility introduction Al 2 O 3 particles into alloy means special master with ultrasonic processing is shown. improvement tensile properties an Al-based composite material reinforced 0.1 wt% EEW demonstrated.
Ultrasonic processing in the cavitation mode is used to produce composite materials based on metal matrix and reinforcing particles of micro-and nano-sizes.In such a case, deagglomeration aggregates uniform distribution are expected effects.Although can not only fragment acoustic field, they also coagulate, coarsen precipitate.In this paper, theoretical study processes coagulation liquid under ultrasonic treatment made.The influence various parameters ultrasound dispersion medium dynamics...
Abstract The effect of metal nanopowders (Al, Fe, W, Ni, Cu, and Cu‐Ni alloys) on the decomposition energetic materials (HMX, AP, AN) with DTA–TGA method was studied it found that catalytic action appears in case three materials. temperature addition could be lowered by 82 °C for AN, 161 96 HMX. reaction mechanism enhancing is discussed.
This work investigated the oxidation, ignition, and thermal reactivity of alloy nanoparticles aluminum copper (nAlCu) using simultaneous thermogravimetric analysis (TGA) differential scanning calorimeter (DSC) method. The microstructure particles was characterized with a electron microscope (SEM) transmission (TEM), elemental composition before after oxidation energy dispersive X-ray spectroscopy (EDS) diffraction (XRD). were heated from room temperature to 1200 °C under different heating...
It has been found that a high electrical conductivity of 63.1%, the International Annealed Copper Standard (IACS), and mechanical properties are achieved by initial aluminum alloy after undergoing four cycles severe plastic deformation (SPD) process. when TiB2 particles introduced into samples subject to SPD, characteristics improved. Microhardness (HV) increases from 329 665 MPa, yield strength (YS) 38 103 ultimate tensile (UTS) 73 165 MPa while maintaining cast without reinforcing...
The number of candidate molecules for new non-narcotic analgesics is extremely limited. Here, we report the identification thiowurtzine, a potent analgesic molecule with promising application in chronic pain treatment. We describe chemical synthesis this unique compound derived from hexaazaisowurtzitane (CL-20) explosive molecule. Then, use animal experiments to assess its activity vivo upon chemical, thermal, and mechanical exposures, compared effect several reference drugs. Finally,...
A series of casting experiments was conducted with A356 aluminum alloys by applying vibration treatment and using Al-TiB2 composite master alloys. The main effects include the promotion nucleation a reduction in as-cast grain size. Using titanium diboride microparticles allows further average size to 140 µm. reasons for this behavior are discussed terms complex effect on melt, considering destruction dendrites, presence additional crystallization centers. Tensile tests were performed samples...
