Hierarchical toughening of laminated nanocomposites with three-dimensional graphene/carbon nanotube/SiC nanowire

Investigation of Mechanical and Wear Behaviour of Al5056-Carbon Nanotube -Graphene Hybrid MMCs using Powder Metallurgy Route

“…Later as graphene is further increased to (5%) i.e., Al-0.5C-5G we can see the reduction compared to 3% Gr in the matrix because of agglomeration due to the addition of more buttressing milieu. This is due to the capacity stentorian ability of the bolstering in the milieu material [16][17][18][19] . From Figure 7 solidity surges with the upsurge in keeping Carbon Nanotube (CNT) continual and Graphene (Gr) gratified in the factual.…”

W/Si3N4 composite ceramics reinforced with core‐shell W‐crystallized oxynitride phase

“…The fracture toughness was determined through the single-edge notched beam method (SENB; standard method) with a span of 16 mm. The SENB fracture toughness was calculated according to the following equations 10 :…”

“…The fracture toughness was determined through the single‐edge notched beam method (SENB; standard method) with a span of 16 mm. The SENB fracture toughness was calculated according to the following equations 10 : $$$$\begin{equation}{\mathrm{\;}}{K_{{\mathrm{IC}}}} = \left[ {\frac{{{F_{{\mathrm{max}}}} \times L \times {e^{ - 6}}}}{{W\; \times \;{B^{3/2}}}}} \right]\;f\left( {\frac{a}{B}} \right)\end{equation}$$$$ $$$$\begin{eqnarray}&&\hspace*{-8pt}f\left( {\frac{a}{B}} \right) =\nonumber\\ &&\hspace*{-8pt} \frac{{3{{\left( {\frac{a}{B}} \right)}^{1/2}} \left[ {1.99 - \left( {\frac{a}{B}} \right)\left( {1 - \frac{a}{B}} \right)\left( {2.15 - 3.93\frac{a}{B} + 2.7{{\left( {\frac{a}{B}} \right)}^2}} \right)} \right]}}{{2\left( {1 + \frac{{2a}}{B}} \right){{\left( {1 - \frac{a}{B}} \right)}^{3/2}}}},\nonumber\\ \end{eqnarray}$$$$where K IC is the fracture toughness (MPa·m 1/2 ), F max is the maximum force (N), L is the support span (m), W is the width of the sample (m), B is the height of the sample (m), and a is the depth of notch (m).…”

Tribological Behavior of Bioinspired Surfaces

“…Along with mechanical properties, the tribology behavior was observed to improve in comparison with aluminum. The research study depicted that laminated ceramic materials are highly reliable in improving the tribological performance of the material surface [ 220 , 221 , 222 ]. Song et al [ 223 ] investigated the friction behavior of Al 2 O 3 /MoS 2 -BaSO 4 laminated material with reciprocating motion.…”
