The Snoek Relaxation in Dilute Ternary bcc Alloys. A Review
No full textThe Snoek relaxation due to interstitial solutes in bcc metals is often affected markedly by the presence of a small amount of substitutional solute atoms. This effect is believed to originate from the interaction between the substitutional and interstitial solute atoms, or the s-i interaction. This review summarizes first the experimental observations on the Snoek relaxation in various dilute alloys such as Fe-M-C/N and V/Nb/Ta-M-O/N, and describes next the theoretical studies on the thermodynamics and kinetics of the relaxation. It is suggested from recent studies that careful examinations of the variation of the spectrum with solute concentrations are useful for quantitative characterization of the s-i interaction
Dislocations in metals and alloys with the hexagonal close-packed structure
No full textAtomistic aspects of dislocations in hexagonal close-packed metals are reviewed. Computer simulation studies on the atomic structure of planar faults and dislocation cores have made essential contributions to understanding the wide variety of the plastic deformation behaviour of this class of materials. Stacking faults have been found to be the most important factor governing the core structure and the glide mechanism of dislocations; the preference for the glide plane, the magnitudes of flow stress and the deformation microstructure in various metals can be understood from the stability of the stacking faults in each material. A brief summary of the deformation behaviour of DO19 ordered alloys and intermetallic compounds is also given, focussing on Ti3Al

Effect of waistline position of clothing on perceived attractiveness
No full textWe investigated the effects of the relationship between the waistline of clothing and the body on the appearance of clothing using a sensory test with Japanese and British participants. Using a three-dimensional clothing simulator, an avatar and five dresses with different clothing waistline (CWL) parameters were created. Evaluation by Japanese participants revealed that a dress for which the CWL position fit the body waistline (BWL) of the wearer was evaluated as being unwrinkled, while the dress with a higher CWL position was evaluated as constricted, slim, and beautiful. However, British participants evaluated dresses for which the CWL position fit the wearer’s BWL and the CWL was 1 cm higher than the wearer’s BWL; these dresses were evaluated as slim, and having a beautiful silhouette. Therefore, the results suggested that there is a specific type of waistline for clothing that is perceived as the most attractive, and this differs between Japanese and British participants. When designing a dress, it is necessary to identify the most suitable position of the waistline to maximize attractiveness, taking into account the consumers’ Kansei in each country
