THE USE OF IONIZING RADIATION FOR THE TUNGSTEN PREPARATION

Abstract

The paper presents the results of experimental studies in the field of radiation material science, in particular, relating to the processes of the ionizing radiation action on the change of the properties of the powder components in the tungsten wire preparation. It is known that the shape and size of the particles are among the most important physical characteristics of the powder, influencing its technological properties, behavior of the pressings during sintering, and often determine the quality of finished products. The use of radiation treatment helps reducing the granularity of the powder, which leads to a significant densification of the solid phase during sintering due to high surface energy and chemical reactivity. The paper shows the applicability of gamma-ray effect in the technology of production of refractory metals, allowing to manage the change in the structure, physico-chemical and mechanical properties.
