“…These etching pits are created due to preferential sputtering of dislocation lines intersecting the surface. According to Savitsky and Burkhanov [56], at plastic deformations of 6-10% the dislocation lines in the bcc lattice are parallel to the direction of the closest packing. But at higher degree of the deformation, a texture is formed.…”

“…Such a comparison permits a conclusion to be drawn concerning the effect of covalency on brittleness [18]. However, high-purity W and Mo single crystals have a rather low yield point [19], and, therefore, the Peierls barrier is not so high. So the covalent character of the chemical bond can hardly be expected to determine solely the brittleness of these metals.…”

In the rigid band approximation the electronic structure of W-Re and Mo-Re alloys is calculated and their band contribution to the elastic moduli Cik. Critical Re concentrations are determined at which electronic topological transitions occur. An analysis of the computational results for C, is invoked to discuss variations in the degree of "covalency" and "metallicity" of the chemical bonds in rhenium-doped tungsten. Consideration is given to the role of the elastic anisotropy constant of W-Re and Mo-Re alloys and to its effect on the individual dislocation mobility and plastic properties of these alloys.In der Naherung starrer Bander wird die elektronische Struktur von W-Re-und Mo-Re-Legierungen und ihr Bandbeitrag zum Elastizitatsmodul Ci , berechnet. Kritische Re-Konzentrationen werden bestimmt, bei denen topologische elektronjsche Ubergange auftreten. Eine Analyse der Computerergebnisse fur Ca wird eingeschlossen, um Anderungen im Grad der ,,Kovalenz" und ,,Metallizitit" chemischer Bindungen in Rhenium-dotiertem Wolfram zu diskutieren. Berucksichtigt werden die Rolle der Konstante der elastischen Anisotropie von W-Re-und Mo-Re-Legierungen und ihr EinfluB auf die individuelle Versetzungsbeweglichkeit und plastischen Eigenschaften dieser Legierungen.

“…In this case, additional sources of influence on the structure appear, the main of them: phase transformations in the metal, temperature gradients, thermal (bulk) and interfacial stresses. It should be emphasized that with TCO, it becomes possible to obtain microstructures with a given dispersion characteristic of the supplied factory steel and structural heterogeneity of welded joints [5,6]. In this case, it is possible to obtain such a fine-grained structure, which is unattainable with conventional types of heat treatment [7,8].…”

Passive fluxgate control of structural transformations in structural steels during thermal cycling

Thermocycler processing (TCO) of metals and alloys belongs to one of the most effective ways to obtain the structure of structural steels with a given degree of dispersion. However, the development of thermocycler processing modes in each case is individual in nature and cannot be mechanically transferred from one material to another. Therefore, it is necessary to consider the structural changes in metals during TCO using examples of steels belonging to different groups so that from the whole variety of processes, dissolution and precipitation of phases, stresses and strains, only those that allow you to obtain a given optimal fine-grained structure are selected. Based on the obtained data, we plotted the dependence of the magnetic field strength Hp on the number of cycles during thermal cycling. A comparative analysis of the obtained results is made and conclusions are drawn on the relationship between the magnetic parameter Hp and structural changes in steels during TCO.
