THE ROLE OF DISLOCATIONS IN THE AGEING OF NaCl + SrCl2 CRYSTALS

Le vieillissement des cristaux de NaCl, SrCl2 déformés à des degrés divers a été examiné à l'aide de mesures de conductivité électrique à 500 °C. Il s'est avéré que les impuretés de strontium (le plus vraisemblablement des inclusions en phase suzuki) forment des agrégats dans tout le volume du cristal hôte et pas particulièrement sur les dislocations de bord. Les résultats quantitatifs s'accordent bien avec la théorie simple de Cottrell. Au cours de cette expérience, nous avons trouvé un coefficient de diffusion Dsr = (2,43 ± 0,7) 10-11 cm2/s pour le strontium en impureté.The ageing of NaCl + SrCl2 crystals deformed to various degrees has been investigated by means of electric conductivity measurements at 500 °C. It has been found that the aggregation of strontium impurity (most likely the Suzuki phase inclusions) takes place in the whole volume of the host crystal, not especially on the edge dislocations. The results are in a good quantitative agreement with the simple Cottrell theory. The diffusion coefficient of the strontium impurity in this experiment was found to be (2.43 ± 0.7) 10-11 cm2 s-1

Effects of Intrinsic Forces in Toroidal Cores Wound of Soft-Magnetic Ribbons

Magnetic anisotropy as shown by hysteresis loops of tape-wound toroidal cores has been inspected as to the specific response of the anisotropy to core-internal forces during and after annealing. The loops of toroids are compared to that of strip samples annealed together in various ambience. The core-internal forces were manipulated by means of different core construction, too. The results show that it is the heterogeneity, which produces the most effective forces. Different annealing-induced ribbon shrinkage makes the cores effectively heterogeneous and governs their magnetic response, whereas inherent ribbon heterogeneity affects the core properties, too, and is essential for homogeneous cores

Effects of substitution of Mo for Nb on less-common properties of Finemet alloys

Particular properties of Fe–Nb/Mo–Cu–B–Si rapidly quenched ribbons were examined. Apart from minor variation, no significant difference due to the Mo for Nb substitution was observed in alloy density and its annealing-induced changes. The same holds for the anisotropic thermal expansion of as-cast ribbon when annealed and for induced anisotropy when annealed under stress. The Mo-substituted ribbons show only slightly higher crystallinity and lower coercivity if annealed in inert gas ambience than in vacuum. Some diversity in surface to interior heterogeneity of the differently annealed ribbons can still be distinguished. Preserving a minor percentage of Nb together with Mo does not seem substantiated to obtain favorable soft magnetic properties of ribbons annealed in inert gas.Fil: Butvin, P..
