Different concentrations of powdered aluminum (Al) or cerium sulfate in the range between 10 and 60 phr were incorporated into styrene-butadiene rubber (SBR) matrices. The physico-mechanical electrical properties vulcanizates measured evaluated. An improvement mechanical according to increased filler loading SBR composites was noted. This finding is reinforced by dispersion values (Lee equation), reinforcing index thermal analysis. dielectric properties, namely relative permittivity (ε')...
This study was focused on the investigation of effect cold rolling reduction mechanism at rates 24%, 40%, 56% and 72% structure, microhardness (Hv), TEC (Thermal expansion coefficient) electrical resistivity Al-20wt.%Sn-1wt.%Cubearing alloy.The results showed that structure properties Al-Sn-Cu alloy have been strongly affected by mechanism.The crystallite size Al-matrix decreased continuously with increasing till then slightly increased reduction.Microhardness continually deformation due to...
The effects of 1, 3 and 5 wt.% Cu additions on structure, Vickers hardness, indentation creep corrosion behaviour Al-5Ti-1B ternary alloy were studied analyzed. exhibited a mixture Al3Ti TiB2 intermetallic compounds (IMCs), Al solid solution. Additions 1 showed the same phases, indicating complete solubility atoms in matrix. In addition, Al-5Ti-1B-5Cu precipitation CuAl2 IMC. Furthermore, decreased particle size This structural increased rapidly hardness number (HV) from 643 to 1395 MPa,...
Abstract Dielectric elastomers with conducting inorganic fillers offer a wide range of uses, including capacitive energy storage, elastomer sensors, actuators, and many more. In this approach, low dielectric loss high constant may be made possible by ternary composites that use metal alloy components as reinforcing fillers. Here, Cu-based was added to acrylonitrile-butadiene rubber (NBR) produce composites. Unfortunately, the Cu–Al–Zn alloy’s material incompatibility matrix typically leads...
The current research presents the development of EPDM rubber including shape memory alloy.The Cu-Al-Zn alloy was modified with coupling agent 3-(Trimethoxysilyl) propyl methacrylate (TMSPM) and then incorporated into Ethylene propylene diene (EPDM) by a 2-roll mill technique.The Cu-alloy behaved as superelasticity capability which can be used in various engineering approaches to smart materials.Microstructure, mechanical, rheological magnetic properties Cu-Al-Zn/EPDM composites studied.The...
Novel nanocomposites comprised polyvinyl alcohol (PVA) as a host matrix and different concentration of magnetite (Fe3O4) nanoparticles barium titanate (BaTiO3) before after treatment with ionic liquid (IL) dopant were synthesized by casting method.Transmission Electron Microscope (TEM) was used to determine the particle size particles under investigation.The morphology samples done Scan (SEM) shows an improvement distribution BaTiO3 inside PVA treatment.X-ray Diffraction Spectra (XRD) has...
This research is to investigate the influence of adding different concentrations (0.0109, 0.0185 and 0.037wt %) La on microstructure, electrical resistivity, Vickers micro hardness (Hv) ultrasonic properties 6201 aluminum alloy comparing (6201alloy +0.021wt%TiB) used in an industry.The results showed that (6201alloy+0.037wt%La) was suitable materials for using conductor than alloys added with0.0185wt%La 0.0109wt% La.It also found measured mechanically resistivity contaning has same trend...
