Abstract The segregation of phosphorus at the metal/scale interface formed upon oxidation of Ni and Ni–20Cr at high temperatures was studied. Auger electron spectroscopy with high spatial resolution was used in combination with thermogravimetric measurements. The chemistry of the interface was related to its microstru…
Abstract Upon addition of Tb 3+ to 16 nucleotides and homopolynucleotides, all of them showed a characteristic green emission from Tb 3+ , but with much different intensity, upon excitation in the aromatic region of bases. The result suggested that nucleotides with at least one carbonyl group in nucleotide bases are b…

The influence of surface properties on the magnetic properties of grain-oriented silicon steel was investigated through measurements of iron losses and magnetic domain patterns in an oxide film-coated and mirror surface-finished specimen, with tensile stress applied in the rolling direction. When the surface roughness…
${\mathrm{Pb}}_{3}$(${\mathrm{PO}}_{4}$${)}_{2}$ has two types of domain walls, the W wall and the W' wall. However, both types of domain walls in ${\mathrm{Pb}}_{3}$(${\mathrm{PO}}_{4}$${)}_{2}$ belong to the W wall, because they both can be represented as crystallographically prominent planes of fixed indices. We wi…
Abstract It will be shown that a consequent modelling of filler‐to‐filler and filler‐to‐matrix contacts and of individual slippage processes allows to describe the mechanical deformation behaviour of rubbers filled with rigid filler particles. The phenomenon of reinforcement turns out to be due to non‐Gaussian rubber…
The core loss mechanism of low loss grade Mn-Zn ferrite in the frequency range from 1 MHz to 10 MHz was investigated. Under the condition of f.B=25 kHz. T, it was found that dielectric loss dominated the core loss at frequencies between 1.1 and 3 MHz, while eddy current loss dominated the core loss at frequencies high…

The effect of annealing on the coercivity /sub j/H/sub c/ of sintered Nd-Fe-B is contradictorily discussed in literature, /sub j/H/sub c/ depends on annealing temperature T/sub A/, annealing time, cooling rate, and details of the chemical composition. In the case of (Nd,Dy)/sub 15/(Fe,Co,Mo,Al)/sub 77/B/sub 8/ a decre…
Abstract Poly(arylene ether)s containing N‐arylenebenzimidazole groups were prepared by the aromatic nucleophilic displacement reaction of two new bis(hydroxyphenyl‐N‐arylenebenzimidazole)s with activated aromatic difluorides in sulfolane at 200°C in the presence of anhydrous potassium carbonate. The bis(hydroxyphenyl…
Abstract Influences of nitrile rubber (NBR, acrylonitrile content 33.5 – 36.5 wt.‐%) on the structure and mechanical properties of poly(vinyl chloride) (PVC)/low density polyethylene (LDPE) blends and its synergism with crosslinking agent have been studied. The addition of NBR to the blend is accompanied by a decrease…
The materials which are applied in modern motor vehicles can be considered to be optimally accommodated to the actual demands. Normally a change of materials is only required if by that a cost reduction can be realized, or if the demands change. Such changes at present or in the near future mainly concern ecological a…
Abstract A structured‐geometry model for dispersed and graded deposits was developed for chemical vapor infiltration of multiply‐woven substrates of carbon filters. An earlier model was modified to allow for two reactants in the feed. The model predicts gas‐phase concentration profiles in the voids of substrates and d…

Semi-solid processing (SSP) of alloys has been used commercially since the early eighties for the manufacture of components in the automobile and aerospace industries. The thrust of the early development has been in aluminium and copper alloys. The nature of the process makes it an ideal candidate for the manufacture…

Submcrometer‐scale magnesium nitride (Mg 3 N 2 ) powder was prepared by low‐pressure chemical vapor deposition, i.e., the reaction of Mg vapor with mixed NH 3 –N 2 gases at 800°C under a pressure of ∼1 kPa. The mixing ratios of NH 3 –N 2 gases were 0% NH 3 –100% N 2 (pure N 2 ), 20% NH 3 –80% N 2 , 40% NH 3 –60% N 2 ,…
The time-of-flight spectrum of high-frequency phonons with both anharmonic decay and mass-defect (isotope) scattering is studied numerically for silicon. For the quantitative description of the spectrum in the whole time domain (from t\ensuremath{\simeq}${\mathit{t}}_{\mathit{b}}$ to t\ensuremath{\gg}${\mathit{t}}_{\m…
The influence of fiber/matrix interactions on the mechanical behavior of ceramic matrix composites is examined on glass matrix composites and mainly on composites made by chemical vapor infiltration (CVI) of a fiber preform by a SiC matrix. Then the relationships between interfaces and features of the stress-strain be…
