The oscillation property of a laser-induced cavitation bubble in a viscous fluid is investigated by a sensitive fiber-optic sensor based on optical beam deflection. The temporal and spatial evolutions of the bubble wall during the expansion and collapse are traced according to sequential waveforms induced by the bubbl…
The rms value of Barkhausen noise and residual stresses were followed as a function of the number of loading cycles in alternating bending fatigue of high strength steel. The measurements were carried out in several directions to ensure that changes in the angular anisotropy of Barkhausen noise could be detected. The…
The results of investigation of kinetics and mechanism for synthetic a-CoS oxidation process are presented in this paper. Based on experimental data obtained using DTA and XRD analysis and constructed PSD diagrams for Co-S-O system, mechanism of synthetic a-CoS oxidation process is suggested. Characteristic kinetic pa…
The purpose of this study was to determine the practicability of an experimental protective clothing by identifying the human body's physiological responses to it as well as the human body's comfort level when wearing it, particularly with the use of a processed charcoal material. The experimental protective clothing…
Oxide dispersion strengthening (ODS) steels have been considered to be very promising for fuel clad materials for high burn-up operation of light water reactor and super critical water reactor. For improving the corrosion resistance, increasing chromium concentration, which often resulted in degradation of mechanical…
The behavior of rod-coil diblock copolymers close to a surface is discussed by using extended scaling methods. The copolymers are immersed in selective solvent such that the rods are likely to aggregate to gain energy. The rods are assumed to align only parallel to each other, such that they gain a maximum energy by f…
In this paper, we predicted the possible mechanical properties and presented the electronic structure of Zr<sub>3</sub>AL<sub>3</sub>C<sub>5</sub> by means of first-principles pseudopotential total energy method. The equation of state, elastic parameters (including the full set of s…
Statement of problem. Acrylic resin is most commonly used for denture bases. However, acrylic resin has week points of volumetric shrinkage during polymerization that reduces denture fit. The expandability of POSS (Polyhedral Oligomeric Silsesquioxane) containing polymer could be expected to reduce the polymerization…
Mechanical spectroscopy is a powerful tool for the study of materials. In particular, it is shown that such a technique can help the characterisation of amorphous materials, whatever their nature (polymer, ceramic or metal). It also provides precious information for the understanding of the mechanical relaxations invo…
In this paper, we report micro-structural characteristics of electroplated Cu thin films with the variation of the current density applied during the electroplating process. We evaluated the surface roughness, the crystalline texture, the resistivity, and the grain size of the thin film in a wide range of current dens…
The phase diagrams of the Ni-Mo-B and Ni-W-B ternary systems in the region of less than 50mol%B were constructed by thermodynamic calculation, based on the data obtained by thermodynamic measurement of the related materials. We found three ternary eutectic points and three or two ternary peritecto-eutectic points as f…
Polylactide (PLA) is a biodegradable, compostable, thermoplastic polymer produced from corn, an annually renewable resource. In moving towards developing a sustainable vehicle, use of materials such as PLA could greatly contribute to the goal of a more environmentally friendly vehicle. To date, several non-automotive…
The stacking fault energies of fcc metals have been calculated by the embedded-atom method for 10 fcc metals, Cu, Ag, Au, Ni, Al, Rh, Ir, Pd, Pt and Pb. The calculated values are in good agreement with experimental results, that of Rh and Ir excepted.
Abstract Hydration‐resistant CaO refractory was synthesized by using lightweight CaCO 3 powder as starting material with MgO addition. The addition of MgO not only promoted densification of the compact by inhibiting the grain growth of CaO, but also modified the microstructure of the clinker. Homogeneous microstructur…
According to experiment photographs and the growing characteristic datum that got from the growth process of the electrical tree,the relationship between electrical tree propagation characteristic and the material morphology in XLPE cable insulation are mainly studied.It is found that,as the influence of uneven congre…
Motion of single-walled carbon nanotubes on graphite substrate is investigated by using molecular dynamics simulation in this paper. Following a relaxation to the equilibrium state, a uniform force is applied to carbon nanotubes for a period of time to set them into motion. After the applied force being removed, carbo…
This paper presents a zero-dimensional mathematical model of a planar 2nd generation coflow SOFC developed for simulation of power systems. The model accounts for the electrochemical oxidation of hydrogen as well as the methane reforming reaction and the water-gas shift reaction. An important part of the paper is the…
A melt-spinnable precursor for SiC based fibers was prepared from blend polymers of polycarbosilane (PCS) and polymethylsilane (PMS). After melt spinning, thermal oxidation curing, and pyrolysis, Si-C-O fibers were obtained. The addition of a small amount of PMS (0.2 or 0.5 mass%) to PCS was effective in increasing th…
As NdFeB sintered magnets have been improved not only in magnetic properties but also in cost-performance, they have been remarkably expanding in the global markets. Especially, motor applications by using NdFeB sintered magnets are rapidly increasing because improvements in motor efficiency are urgent to reduce CO2 e…
The cubic phase structure of 4′‐n‐hexadecyloxy‐3′‐cyanobiphenyl‐4‐carboxylic acid (ACBC‐16) was examined by X‐ray diffraction. Unlike the octadecyloxy homologue showing an Im3m‐type cubic phase, the cubic phase of ACBC‐16 was of Ia3d type, both on heating and on cooling, similarly to the corresponding nitro‐substitute…
