Using hierarchical composite approach to improve mechanical response of Mg and Mg–Bi2O3 nano-composites
(
Elsevier, Ltd
, 2013 , Article)
Novel Mg nano-composites reinforced with either Bi2O3 nano-particles or hybrid Al–Bi2O3 particles (Bi2O3 nano-particles hybridized with Al using ball milling) have been synthesized, in this work, through powder metallurgy ...
Enhanced performance of nano-sized SiC reinforced Al metal matrix nanocomposites synthesized through microwave sintering and hot extrusion techniques
(
Elsevier B.V.
, 2017 , Article)
In the present study, nano-sized SiC (0, 0.3, 0.5, 1.0 and 1.5 vol%) reinforced aluminum (Al) metal matrix composites were fabricated by microwave sintering and hot extrusion techniques. The structural (XRD, SEM), mechanical ...
Hierarchical honeycomb auxetic metamaterials
(
Nature Publishing Group
, 2015 , Article)
Most conventional materials expand in transverse directions when they are compressed uniaxially resulting in the familiar positive Poisson’s ratio. Here we develop a new class of two dimensional (2D) metamaterials with ...
Using B4C nanoparticles to enhance thermal and mechanical response of aluminum
(
MDPI AG
, 2017 , Article)
In this work, Al-B4C nanocomposites were produced by microwave sintering and followed by hot extrusion processes. The influence of ceramic reinforcement (B4C) nanoparticles on the physical, microstructural, mechanical, and ...
Properties of nanoclay PVA composites materials
(
Hamad bin Khalifa University Press (HBKU Press)
, 2013 , Article)
Polyvinyl alcohol (PVA)/Na-rich Montmorillonite (MMT) nanocomposites were prepared using solution method to create polymer-clay nanocomposite (PCN) material. The PCN material was studied using X-ray diffraction (XRD), ...
High strength, ductility, and electrical conductivity of in-situ consolidated nanocrystalline Cu-1%Nb
(
Elsevier Ltd
, 2018 , Article)
Nanocrystalline metals—with grain sizes less than 100 nm— have strengths exceeding those of coarse-grained and even alloyed metals [1], [2]. A bulk nanocrystalline Cu-1%Nb alloy was synthesized by an in-situ consolidation ...
Synthesis and properties of HA/ZnO/CNT nanocomposite
(
Elsevier Ltd
, 2018 , Article)
The goal of this study was to examine the tribomechanical properties of hydroxyapatite (HA)/ZnO and HA/ZnO/CNT composite ceramics (carbon nanotubes; with different ratios 0.5 wt%, 1.0 wt%, and 1.5 wt%). The composites were ...
Enhancing thermal and mechanical response of aluminum using nanolength scale TiC ceramic reinforcement
(
Elsevier Ltd
, 2018 , Article)
the present work, nano-sized titanium carbide (0.5, 1.0 and 1.5 vol%) reinforced aluminum (Al) metal matrix composites were synthesized by powder metallurgy incorporating microwave sintering and hot extrusion. Microstructural, ...
Comparison between microwave and conventional sintering on the properties and microstructural evolution of tetragonal zirconia
(
Elsevier Ltd
, 2018 , Article)
In this research, the comparison between microwave sintering and conventional sintering on the mechanical properties and microstructural evolution of 3 mol% yttria-stabilised zirconia were studied. Green bodies were compacted ...
Effect of microwave sintering on the properties of copper oxide doped Y-TZP ceramics
(
Elsevier Ltd
, 2018 , Article)
The effect of various amounts of copper oxide (CuO) up to 1 wt% on the densification behaviour and mechanical properties of 3 mol% yttria-tetragonal zirconia polycrystal (Y-TZP) were studied by using microwave (MW) sintering ...
