THE INFLUENCE OF TECHNOLOGICAL PARAMETERS ON STRUCTURE FORMATION AND PROPERTIES OF COMPOSITE ТІ-ТІВ-ТІС
Abstract
It was established that the formation of titanium matrix composite depends not only on the size and number of phase components formed by diffusion interaction, but also on the concentration of initial components, temperature and time. Using optical microscopy and methods of X-ray diffraction and X-ray analyzes, it was estimated that the resulting composite is titanium matrix pierced with titanium boride needle inclusions and small dendroid inclusions of titanium carbide. It was established that under high-speed electron beam sintering it is possible to obtain a composite with higher mechanical properties than under radiation sintering. Complex investigation of patterns of titanium matrix composite Ti-TiB-TiC structure formation depending on the amount of boron carbide additive to the starting mixture and sintering method can be effectively used for manufacturing titanium alloys in return of some industrial alloys in aviation industry.
