Zirconia (ZrO2) and alumina (Al2O3) based ceramics are widely used for load-bearing applications in bone repair due to their excellent mechanical properties biocompatibility. They often regarded as bioinert since no direct bone–material interface is created unless a porous structure intercedes, leading better bonding. In this regard, investigating interactions between cells of great interest. the present study, we report on successful fabrication sintered A-61, zirconia Z-50 zirconia/alumina...
Two classes of composite materials are considered: classical metal–ceramic composites with reinforcing hard inclusions as well ceramics matrix soft gel inclusions. Movable cellular automaton method is used for modeling the mechanical behaviors such different heterogeneous materials. The based on particle approach and may be considered a kind discrete element method. main feature use many-body forces inter-element interaction within formalism simply deformable approximation. It was shown that...
Abstract This paper considers the deformation of Al/B 4 C and NiTi/TiC composites 6061T6 aluminum alloy with double-layer composite coatings reinforced by B TiC particles. Three- two-dimensional dynamic problems are solved numerically using Abaqus/Explicit. The thermomechanical behavior homogeneous matrices substrates is modeled an isotropic elastic-plastic formulation. nitinol matrix implies possibility a completely reversible elastic phase transition from austenite to martensite upon...
Porous ceramics obtained from ultra-fine powders have been studied.the porosity of ceramic samples was found between 15 to 80 %. the structure materials a cellular structure.A distinctive feature all deformation diagrams in experiment their nonlinearity at low deformations which described by parabolic law. it shown that observed nonlinear elasticity for on is due mechanical instability elements carcass.
It has been studied a porous ceramics obtained from nanocrystalline ZrO2 powders. Samples were by pressing and sintering of compacts, the porosity ceramic samples was 20 to 80%. The average grain size in increased 0.4 4 microns with increasing temperature duration isothermal holding 1400 1600 °C 1 5 hours, respectively. shown that "stress – strain" diagrams on initial stage deformation nonlinear behavior high parabolic factor strain-stress curves. fracture materials observed elastic area...

Porous zro 2 -Al o 3 ceramics produced from powder mixtures of zirconia and aluminum hydroxide obtained by different methods is studied.the paper presents the data on structure, phase composition, crystal structure strength studied ceramics.it found that sintered composites depends type used in initial mixture.the pore size shown to depend sintering temperature.the crystallite determined at which become solid.
in this research the layers of a Hungarian conventional brick clay deposit were examined both on material and mineralogical structures compositions as well technological properties.During their examination authors have found that volumes X-ray amorphous submicron nano particles clays do not influence dry sensitivity extruded formed green products.the also strong correlation between raw materials bending strengths sintered ceramics.As more are higher produced from them ceramics.
the structure and phase composition of zirconia-based nanosystems are studied.it is shown that during mechanical activation this nanosystem divided into two subsystems with average size structural elements differing by orders magnitude.the fraction quasiamorphous (X-ray amorphous) therewith increases.through varying heating rate such a in sintering we may purposefully vary its shrinkage at stage isothermal sintering.it through variation one can stage.the higher temperature, slower compaction...
The paper studies the influence of heat treatment modes on structure and properties austenitic steel grade 08Kh18N6AG10S. Austenitic with twinned boundaries was preserved after quenching at 1040 1100 ℃. At same time, average size grains decreased from 42.3 ± 6 μm (supply condition) to 38.1 5.0 39.0 4.5 μm, respectively. Quenching ℃ leads release excess carbide phases grain boundaries. Mainly manganese silicon oxides were found a slight decrease in microhardness (by 12 %) compared condition...
The article studies the porous ceramics consisting of ultra-fine ZrO2 powders. porosity ceramic samples varied from 15% to 80%. structure materials had a cellular configuration. distinctive feature all experimentally obtained strain diagrams is their nonlinearity at low deformations characterized by parabolic law. It was shown that observed nonlinear elasticity for in due mechanical instability elements framework.
