Materials prepared by directional solidification.
Technology of directional solidification is based on controlling of solidification process of melted alloy in the manner of achieving of columnar grain or single crystal growth with required crystallographic orientation.
Materials prepared by directional solidification are characterised by excellent mechanical properties and high quality. This technology allows to increase significantly toughness of some brittle polycrystalline materials, to improve high temperature strength and producing near net-shaped castings with minimal requirements on finishing operations. The technology is developed for processing of single crystals from pure metals and alloys (including superalloys), fibre or lamellar eutectic composites, intermetallic alloys and superconductors.
Materials prepared by directional solidification are designed predominantly for high temperature applications (parts of gas turbines), electrotechnics (superconductors and semiconductors) and for production of precise equipments (single crystals for calibres)
The technology is on high level of development, for some applications it is possible to established it to practice.
Preparation of single crystals, materials with columnar structure, eutectic composites and superconductors from alloys with a melting temperature up to 1600*C on demand.
