“…Generally, single crystals of refractory metals with bcc-lattice prepared using these techniques are characterized by a specific dislocation substructure with the size of subgrains, which can be divided into three orders of magnitude. [1,4,9,[11][12] The more developed substructure is typical for crystals prepared by plasma-arc melting in comparison with EBFZM. The formation of dislocations and substructure of single crystals grown from the melt depends on the axial and radial thermal stresses during growing and cooling of single crystals, the impurity and alloying elements concentration gradients in the solid phase, the lattice supersaturation with vacancies, the substructure inheritance of the seed crystal into the growing crystal, etc.…”

“…The formation of dislocations and substructure of single crystals grown from the melt depends on the axial and radial thermal stresses during growing and cooling of single crystals, the impurity and alloying elements concentration gradients in the solid phase, the lattice supersaturation with vacancies, the substructure inheritance of the seed crystal into the growing crystal, etc. [4] The dislocation density of these single crystals was about 10 5 -10 6 cm À2 , in case of plasma-arc melting up to 10 8 cm À2 . [1,4,9] At investigation of macrostructure of single crystals of tungsten and molybdenum on the surface of the crystals, alternating light and dark strips were observed as a result of various etching of edges ( Figure 2).…”
