The paper covers the study of influence equal-channel angular pressing (ECAP) on structure, crystallographic texture, mechanical properties and electrical conductivity Cu-ETP copper (Russian analogue – M1), as well dependence these characteristics orientation measurement direction relative to cross-section (from −45 90°). specific strength material in as-delivered condition (hot-rolled) effect annealing at a temperature 450 °C original sample are investigated. Mechanical tests for uniaxial...
High-density electric current pulses increase the plasticity and reduce yield strength of metals with negligible heat generation. This effect has great potential for development energy-saving processing technologies hard-to-deform metallic materials. Despite long history studying electroplasticity, there is still no consensus on physical nature this effect. In paper, repetitive applied at same or gradually increasing tensile stress plastic deformation copper wire investigated using a...
From the positions of system analysis and theory optimal design approach to development hardware industrial production carbon nanotubes by-ptoducts on basis their functionalized forms is proposed. Functionalization carried out by oxidation with concentrated nitric acid subsequent modification titanium stearate. Functionalized this method, have increased hydrophobic properties are semi-products for use in composites based non-polar matrices. Material flows analyzed. Interrelations between...
In the modern literature, there are practically no data on electrical characteristics of bituminous binders modified with carbon nanotubes and graphene nanoplates, while they necessary for design development innovative asphalt pavement compositions sensitive to super-high-frequency microwave radiation. Contemporary multi-component systems that may contain polymers, rubbers, synthetic or natural resins, inorganic salts, even fragrances. As a result application modifying additives, bitumen...
Abstract The present paper considers the efficiency of using carbon nanotubes (CNTs) functionalized by titanium stearate groups for modifying polyethylene and polypropylene. For this purpose, strength characteristics, Shore hardness, thermal diffusivity conductivity obtained nanocomposites were determined. weak effect CNTs (0.01-1.5 wt.%) on values coefficients was revealed. It found that compared to unmodified matrix, containing 0.01-0.1 wt.% stearatefunctionalized demonstrate, an increase...
The present paper considers the sedimentation and aggregation stability of carbon nanomaterials with various morphologies (carbon nanotubes CNTs, graphene nanoplatelets GNPs) in compositions based on I-20A industrial oil. CNTs GNPs were treated different ways to form functional groups and/or modifying layers surface thereof. modification using titanium-stearate higher carboxylic acids improves their dispersion yields more stable oil for applications.
Modifying additives are introduced into the composition of modern bituminous binders to meet high requirements for performance road surfaces. The use carbon nanomaterials as modifiers imparts antistatic properties and opens up possibility applying an innovative approach healing cracks in asphalt pavement under action microwave radiation with its subsequent regeneration. A series samples nanocomposite materials based on BND 60/90 bitumen hybrid filler containing graphene nanoplatelets (GNPs)...
The paper analyzes the known methods for synthesizing low-defect graphene nanoplatelets (GNPs) of different structure. optimal GNP synthesis procedure was determined - namely, intercalation natural graphite using peroxosulfate compounds, exfoliation obtained removal intercalant, and ultrasonic treatment under various conditions. This technique allows production GNPs with a thickness less than 10 layers. Furthermore, method surface modification synthesized titanium stearate developed to...
Abstract For the first time, in analysis of behavior a nanodispersed material ( i.e. , its outflow and batching from hopper unit, as well movement mixing), conventional approach was used to calculate hardware technological design functionalization. Besides, features layer single nanoparticles applied feeding process under vibrations, along guide blade pouring flow into receiving tank were considered, dependencies formulated, recommendations given for designing assembly materials. The results...
In this study, we synthesized samples of nanoporous carbon materials (NCM) from polymer raw materials. The influence the conditions synthesis process (the mass ratio activating agent to precursor) on structure obtained has been studied. Varying precursor made it possible obtain microporous, micromesoporous, and mesoporous Methane adsorption researched in a wide pressure range. highest methane, equal ≈ 20 mmol/g at 100 bar 298 K, is achieved sample with KOH carbonized 6:1 (6NCM).
