Abstract
Monocrystalline tungsten and its alloys are of interest in the design and manufacture of high temperature facilities operating at high (up to 2500 °C) temperatures in vacuum under mechanical loads. This paper demonstrates advantages of using monocrystalline tungsten as a structural material in high-tech industry in comparison with polycrystalline materials. The results of comparative studies of the thermophysical properties of polycrystalline and monocrystalline tungsten 4% tantalum alloy are presented. It is shown that monocrystalline tungsten based materials are more suitable for use under high temperatures and high mechanical stresses than polycrystalline. Use of monocrystalline tungsten as a structural material makes it possible to prolong the service life of modern technical facilities.
