“…Solid-state single crystal growth was first observed and studied in metals as a possible alternative to very difficult and expensive procedures used to fabricate metal single crystals. Most of the research on single crystal conversion in metals date to the middle of the last century and include the reports on single crystals of Fe, Mo, W, and other metals [17][18][19]. Later on, in the early 1980s, applying the same principles observed in the metal systems, Matsuzawa and Mase [20,21] performed research on the growth of single crystals from various polycrystalline oxide materials, including ferrites, garnets, and spinels.…”

Fabrication of single crystals has long been limited to melt-and solution-growth techniques. However, in recent years solid-state single crystal growth (SSCG) has appeared as a promising alternative to the conventional techniques due to its cost-effectiveness and simplicity in terms of processing. Moreover, the SSCG technique has enabled the fabrication of single crystals with complex chemical compositions and even incongruent melting behavior. A recently proposed mechanism of grain boundary migration known as the "mixed control mechanism" and the associated principles of microstructural evolution represent the basis of the SSCG technique. The mixed control mechanism has been successfully used to control the key aspects of the SSCG technique, which are the grain growth and the development of the microstructure during the conversion process of the single crystal from the polycrystalline matrix. This paper explains in brief basis of the mixed control mechanism and the underlying principles of microstructural evolution in polycrystalline materials and provides a comprehensive overview of the most recent research on single crystal materials fabricated via the solid-state single crystal growth technique and their properties.

“…Its elastic-plastic deformation under (quasi-) static loading has been well studied. [12][13][14][15][16][17][18][19][20][21][22][23][24][25] The plastic deformation of Mo is dominated by the motion of screw dislocations. [19][20][21][22][23][24][25] In BCC metals including Mo, due to its nonplanar structure, the mobility of screw dislocations is significantly lower compared to that of edge dislocations.…”

To investigate the role of crystal anisotropy on the elastic-plastic deformation of BCC single crystals at high shock stresses, molybdenum (Mo) single crystals were shock compressed along the [100], [111], and [110] orientations at elastic impact stresses between 20 and 110 GPa. Laser interferometry was used to measure shock wave velocities and particle velocity histories. Along the [100] and [111] orientations, elastic-plastic waves (two wave structure) were observed up to 110 GPa. Along the [110] orientation, the two wave structure was observed only up to 90 GPa. The measured elastic wave amplitudes were analyzed to determine crystal anisotropy effects, impact stress dependence, and the activated slip systems on the Hugoniot elastic limit. The findings from our work have provided insight into the role of crystal anisotropy on the elastic-plastic deformation under shock compression at high stresses.

Als Wege zur Züchtung von Einkristallen bieten sich grundsätzlich alle allgemeinen Methoden des Kristallisierens an, die gewöhnliche Lösungszüchtung, die Hydrothermal‐Züchtung, die Züchtung aus Schmelzen, die Züchtung nach dem Verneuil‐ oder dem Flammenschmelz‐Verfahren, die Züchtung aus gasförmiger Mutterphase, die Züchtung durch Rekristallisation im festen Zustand und die elektrolytische Kristallisation. Alle diese Züchtungen, die nachfolgend beschrieben werden, sind auch, allerdings mit sehr unterschiedlichem Erfolg, technisch benutzt worden.
