Effect of the warm processing parameters (the strain rate, forming temperature and deformation degree ) on the γ' metastable phase transformation in 2205 duplex stainless steel has been studied. The γ' metastable phase was located within the ferrite phase. Dynamic recovery took place only within the γ phase, and dynam…
In this report the results on the investigation of magnetic states of Fe and Co ions in superlattice [Mo(12Å)Co(21Å)Fe(14Å)]*100 are presented. The magnetic superlattices were obtained by means of cathode sputtering in discharge with oscillating electrons. The results of X-ray diffraction show that magnetic superlatti…
There is proposed the nonlinear model of dose dependence saturation of the yield strength on the base of the vacancy and interstitial barrier interaction in this work. Processes of mutual recombination of vacancy and interstitial barriers and formation of vacancy and interstitial clusters are taken into consideration.…
Poly(ether sulfone)s (PES) containing 25-75 mol % valeric acid were prepared with bisphenol A, bis(4-chlorophenyl)sulfone and 4,4-Bis(4-hydroxylphenyl)valeric acid using potassium carbonate in DMAc (dimethylacetamide) at 160 °C. Copolymers containing carboxylacid group were reduced to hydroxy group by BH3 solution 1M…
Abstract Saponification of methyl dodecanoate with an aqueous sodium hydroxide solution in the absence and presence of alcohols was studied using a tubular reactor made of silicone tube to elucidate effects of alcohol addition on the saponification. The reaction rates of saponification were accelerated significantly w…
Double-patterning generation at 32-nm node and beyond raises many subjects for photomask blanks. We especially focus on the resolution improvement by hyper-thin resist combined with the hardmask process called the hyper-thin resist system (HTRS). Cr-hardmask has been specially developed for the HTRS, and this Cr mater…
New cup-type diamond-grinding-wheels with hexagonal pattern have been developed. Grinding stone ratio, R is defined as the ratio between the hexagonal edge area containing abrasive grains and the total area of the wheel surface. In the present work, four kinds of hexagonal grinding wheels with different R (13 %, 19 %,…
Grain boundaries significantly influence the properties of polycrystalline metallic materials, particularly with grain sizes in the nano-metre range. The effect of grain boundaries on plasticity, fracture and corrosion resistance is well documented experimentally. The aim of this paper is to show that recent progress…
Konjac Glucomannan (KGM) was modified by maleic anhydride (MA). The influences of processing parameters on the mechanical properties of KGM films were investigated through orthogonal experiments. The results showed that the effects of pH, temperature and time of KGM swelling on tensile strength and folding endurance o…
Electron coherent and incoherent pairings and other types of correlations are studied exactly for the ensemble of small clusters with different geometries under variation of interaction strength, electron doping and temperature. Charge and spin collective excitations yield intriguing insights into level crossing degen…
The electrochemical properties of single crystals of cerium fluoride alloyed with bivalent cations Sr 2+ , Ca 2+ , Ba 2+ , Sr 2+ + Ca 2+ , Sr 2+ + Ba 2+ , Ba 2+ + Ca 2+ and also with La 3+ and La 3+ + Ba 2+ cations are studied using the dynamic voltammetry and impedance spectroscopy. The conductivity of symmetrical ce…
A method is suggested, which enables one to determine the interfacial tension on the interface between stratifying liquids using the equipment for measuring the ultrasonic velocity by the pulse-phase method. This method is employed for measuring the temperature dependences of interfacial tension in Ga-Bi and Ga-Pb sys…
The development of polymer-layered silicate nanocomposites (PNCs) includes a long list of different possible components such as polymers, nano-additives, and co-additives, together with surface chemistry and various processing conditions. This involves the investigation of a large number of parameters that influence P…
By means of X-ray fluorescence with synchroton radiation (XRF-SR), the contents of all 14 rare-earth elements (REEs) and that of Y were determined in 12 monazite samples from different veins in the Ilmen’ Reserve (South Urals). It was found that, in anphibole-micaceous-carbonate mineralized zones within metabasites, m…
Organic-inorganic photovoltaic systems which attempt to integrate benefits of both material types in terms of ease of fabrication, stability and efficiency are reviewed. Three broad categories; inorganic-small molecule systems, carbon naotube incorporated organic photovoltaics and nanostructured organic surfaces-based…
We report results of the study of the recently discovered magnetic resonance in CeB6, which is characteristic to the phase II in the magnetic phase diagram of this strongly correlated heavy fermion metal. Experiments were carried out in a wide frequency range /2=44-360 GHz in magnetic field up to 30 T. It is found t…
The elastic properties of pure polycrystalline Pu were investigated as a function of temperature by resonant ultrasound spectroscopy. For both alpha and gamma phase, shear (G) and longitudinal (CL) elastic moduli were determined simultaneously and the bulk modulus (B) was computed from them. In alpha phase, G and B ex…
The Journal of Micro/Nanopatterning, Materials, and Metrology (JM3) publishes peer-reviewed papers on the core enabling technologies that address the patterning needs of the electronics industry.
Corrosion studies were carried out using potentiodynamic polarization method on amorphous, nanocrystalline and crystalline states of the alloy Ti60Ni40 in 0.5 M H2SO4 and 0.5 M HNO3 aqueous media at room temperature. The nanocrystalline state of Ti60Ni40 was obtained by removing about 10 μm from the air side surface (…
