Normalizing of hot rolled bands results in better magnetic properties (lower iron loss and higher flux density) than non‐normalizing, which is caused by the fact that normalized steels show larger final grain size, higher volume faction of cube texture, and lower volume fraction of γ fiber than non‐normalized ones. An…
The glass formation in the ZrF 4 -BiF 3 - Me F ( Me = Li, Na, K) systems is investigated. Bismuth fluorozirconate glasses are synthesized in this system, and their thermal and optical properties are described.
An interformational exfoliation behavior of the layered Ti3AlC2 induced by copper was firstly investigated via a “Cu-Ti3AlC2-Cu” sandwich sample infiltration-sintered at 1100oC to 1200oC. It was found that the molten Cu accelerates Ti3AlC2 to decompose, induces the interformational exfoliation to generate, and consequ…
The method of molecular dynamics is used to investigate, on the atomistic level, the microscopic mechanisms of elastoplastic deformation and of the loss of continuity in crystalline iron under high-rate extension. Cases of uniaxial and uniform extension are considered. The model of realistic embedded-atom many-particl…
This paper presents a technique for modeling of asymmetric domain rotation in magnetic materials. The technique uses a variable pinning strength, instead of a constant, to model the asymmetry. This allows modeling of quasi-static hysteresis effects, which show very good agreement with measurements for different magnet…
The Japan Atomic Energy Agency (JAEA) is carrying out R&D for constructing the facility of high intensity spallation neutron source which may bring us innovative science fields. A high power pulsed proton beam will be injected into a mercury target for nuclear spallation reaction. Due to the pulsed proton injection, m…
We report on structural and optical properties for Zn1-xMgxO (ZMO) thin films produced by pulsed laser ablation. ZMO thin films were grown on a-plane Al2O3 substrates at 400°C. In order to efficiently incorporate Mg into ZnO thin films, we used multiple ZnO-MgO ablation targets. Pulses from a Nd:YAG laser (4th harmoni…
Poly(propylene) was RF sputtered in a working gas mixture of argon and nitrogen using planar magnetron. With nitrogen content in the mixture increasing from 0 to 100%, the deposition rate of plasma polymer films increased from 3 to 12 nm · min−1, the contact angle of water on sputtered plasma polymer films decreased f…

The total stability constants of Th4+, U4+, Np4+, Pu4+, Am4+, Cm4+, Ce4+, Tb4+, Pr4+, Tb3+, and Pr3+ complexes with P2W17O 61 10− heteropolyanion in 1 M sodium salt solutions at pH ≥ 5.5 (i.e., when the anion is not protonated; so-called “absolute” constants), were determined experimentally or calculated from publishe…
A new phenomenon in highly oriented semicrystalline polymers has been found—the occurrence of amplitude‐modulated oscillations (or beatings). The beatings appeared for certain external conditions. A preliminary interpretation of the phenomenon is given at the supermolecular level.
This note describes the scour induced by tidal currents around piles under live-bed conditions, on the basis of physical model tests carried out at Aalborg University (DK). Fine sand was placed in a flume equipped with a reversible pump. Scour was leveled by an automatic laser profiler. Experimental time evolution of…
This paper generalizes a 2-D isotropic vector hysteresis model represented by the superposition of scalar stop models. Its identification method and property of rotational hysteresis loss are discussed. The generalized vector model can control its rotational hysteresis loss

In this study, we report on the synthesis of nanopowders of ferroelectric Bi 3.5 Nd 0.5 Ti 3 O 12 ceramic at temperatures below 500°C via a simple chemical method using citric acid as a solvent. The calcined powders were characterized using X‐ray diffraction (XRD), differential scanning calorimetry (DSC), and transmis…
Transmission electron microscopy has been used to study the microstructure of ordering Cu 3 Pd alloys. The effect of atomic ordering of the alloys on their electrical, magnetic, and optical properties has been studied.
Neutronics experiments have been performed for the solid breeder blanket using a DT neutron source at the FNS facility in JAEA. We have applied the blanket mockup composed of two enriched Li2TiO3 and three beryllium layers, and measured the detailed spatial distribution of the tritium production rate (TPR) using enric…
The influence of the replacement of Mn ions in the La0.7Ca0.3Mn1 − y Fe y O3 compounds (0 ≤ y ≤ 0.09) by another transitional metal, Fe, was studied. The radii of both ions are almost identical, which makes the effect of the transitional metal on the physical properties of manganites more transparent. The crystal stru…
Aluminium and its alloys play an important role as anodic materials in sacrificial protection. Many well-known zinc sacrificial anodes are prone to passivation, which reduces their protective activity. For that reason it was necessary to find an anodic material in which the passive state of the protector has been disr…
The complex tris(thenoyltrifluoracetonate)(2,2'-bipyridine)europium(III), Eu(tta)3bipy, was synthesized and assessed for luminescence behavior. The emission of its blends with poly(9-vinyl carbazole) (PVK-Eu), varying in composition from 1 to 8% (Eu(tta)3bipy/PVK, m/m) showed PL at 425 nm and at 613 nm, with intensiti…
