Abstract
The results of experimental studies in the field of radiation materials science, in particular, the phenomenon of chemical bond transformation in metal powders subjected to ionizing radiation in producing tungsten wire are presented. The phenomenon of energy conversion of an intracrystalline chemical bond between a material and a complex, including point defects and impurity atoms, leading to a change in the structure of sinter powder crystals, has been established experimentally.
Highlights
The development and use of advanced methods of improvement of technology in powder metallurgy is a priority direction limiting the development of many areas of science and technology
The results indicate the possibility of controlling the structure by irradiating polycrystalline powder particles in the technology for producing tungsten wire, which leads to a decrease in the tendency of products to recrystallize and increase the mechanical and physicochemical properties that are inaccessible to macro-technologies
Tungsten wire is characterized by high plasticity, which allows increasing the winding speed of the helix, and imparting specific properties ensures the operation of products under extreme conditions [1, 2]
Summary
The development and use of advanced methods of improvement of technology in powder metallurgy is a priority direction limiting the development of many areas of science and technology. Understanding the structure of chemical bonding in irradiated samples is the key to solving problems in radiation physics, and in the production of amorphous metals and their alloys the scientists from many countries are working on.
