Effects of chromium (Cr) and molybdenum (Mo) on differences in corrosion behavior of ferritic and austenitic stainless steels (SS) were investigated to clarify the reason for the superior corrosion resistance of high-alloy ferritic SS to austenitic SS. In the region where the corrosion index (Cr + 3xMo [mass%]) exceed…
Abstract Explains the origins of the development of the handle method, and lists the three criteria for predicting fabric quality. Shows how fabric handle evaluation is used, for example, handle analysis expresses characteristics and quality. Goes on to explain hand value and total hand value with the aid of equations…

Two novel dinuclear complexes of terbium(III) with 1,5-bis(1′-phenyl-3′-methyl-5′-pyrazolone-4′)-1,5-pentanedione (H2L), Tb2L3·6H2), Tb2L3·SDMF, have been synthesized. The crystal structure of Tb2L3 · 5DMF was determined by X-ray diffraction methods. Crystals are triclinic, space group P 1 with α = 16.957(5), b = 17.8…
High-pressure experiments on metallic thallium have been carried out using a diamond-anvil cell for pressures up to 32 GPa. A hexagonal close packed → face-centred cubic (f.c.c.) phase change takes place around 4 GPa. Fitting of the experimental data to the Murnaghan and Birch equations of state has been used to obtai…
Th e effect of silicon on the microstructure and solidification segregation of directionally solidified IN738 nickel-based superalloy was studied. Directional solidification at various solidification rates and partial directional solidification plus rapid quenching were applied. Metallographican alysis and an electron…
The gaseous alkali corrosion kinetics of Si 3 N 4 were systematically investigated from 950° to 1100°C in dry air containing 0.98 vol% sodium nitrate vapors. The linear reaction rates observed at all temperatures indicate that the alkali corrosion of Si 3 N 4 is interface‐controlled with an activation energy of 199 kJ…
Abstract The title organic charge transfer salt, where EP-TTP is 2-(4,5-ethylenedithio-1,3-dithiol-2-ylidene)-5(4,5-trimethylenedithio-1,3-dithiol-2-ylidene)-1,3,4,6-tetrathiapentalene, has so-called β-type donor arrangement, but the Fermi surface is basically one-dimensional. This salt exhibits metallic conductivity…
The nonlinear optical response of semiconductor interfaces using three-wave mixing experiments in general, and second harmonic generation (SHG) in particular, has been widely studied, but it is only recently, with the advent of commercial tunable pulsed laser sources, that the spectroscopic aspect of SHG can be more r…
Existing models for predicting end breakage rates in spinning give unrealistic values when considering the effects of changes in count or speed on the worsted ring frame. A new approach to predicting end breaks gives results that are closer to experience values. The most important factor in determining end breaks is y…

Abstract Based on previous work, where it was shown that 4‐urazoylbenzoic acid (U4A) groups, which are attached statistically to polybutadiene, form ordered supramolecular arrays in the unpolar polymer matrix, the present work describes the synthesis of a new molecular building block capable of self‐assembling in the…
The purpose of this study was to compare the experimental dissolution rates of carbonated apatite (CAP) pellets in acidic acetate buffers under a variety of conditions with theoretical predictions. The theoretical predictions were made in the following way. Recently obtained data on metastable equilibrium solubility (…
Abstract The new ferric sulphate mineral, mikasaite, the Fe analogue of millosevichite was found in Ikushunbe tsu, Mikasa city, Hokkaido, Japan. Mikasaite occurs as a sublimate around fractures from which coal gas escapes. The white-light brown coloured mineral shows aggregates of fine porous crystals. The SEM microgr…
Large synthetic diamonds grown by the reconstitution method, all exhibiting the growth forms {100}, {111}, {110} and {113}, were studied. Crystal perfection was assessed by X-ray topography using a conventional source of Cu Kα1 radiation and employing the section, projection and limited-projection topographic techniqu…
Microstructure and crystallinity of a porous silicon (PS) layer formed on a highly doped n-type silicon substrate were examined in detail, and the luminescent nature of the PS layer was also studied qualitatively. A layered pore structure developed after about 3000 s of anodization, and pore morphology became simpler…
Abstract A statistical mechanical theory is presented for liquid‐crystalline polymer solutions, where the liquid‐crystalline polymer is regarded as a wormlike spherocylinder interacting by the hard‐core repulsion and a soft (attractive or electrostatic) interaction with other spherocylinders. The theory is based on th…
The effects of β‐SiC whisker addition on the microstructural evolution and fracture toughness ( K IC ) of hot‐pressed SiC were investigated. Most of the whiskers added disappeared during the densifcation process by transformation into the α‐phase. The remaining whiskers acted as nuclei for grain growth, resulting in t…
