In this paper the properties of the austenitic stainless steel reinforced with various volume fractions of TiB₂ ceramics have been studied. The high pressure- high temperature (HP-HT) method of sintering was applied to the formation of composites. Samples were sintered at pressure of 5 and 7 ±0.2 GPa and temperatures of 1273 K and 1573 K. For the tested materials, the relative density, Young’s modulus and hardness were measured. In order to investigate the structure changes, the scanning electron microscope was used. The obtained results show that the temperature and pressure influence on the mechanical and physical properties of the investigated composites.

W prezentowanej pracy zbadano właściwości stali austenitycznej z różnym udziałem objętościowym ceramiki TiB₂. Do wytworzenia spieków kompozytowych proszków zastosowano spiekanie wysokociśnieniowe HP-HT. Próbki były spiekane przy ciśnieniu 5 oraz 7±0.2 GPa i temperatururze 1273 K oraz 1573 K. Kompozyty poddano badaniom gęstości, modułu Younga oraz twardości. Badania mikrostruktury przeprowadzono za pomocą skaningowej mikroskopii elektronowej. Uzyskane wyniki badań wykazały, że temperatura oraz ciśnienie wpływają na mechaniczne oraz fizyczne wł aściwości materiałów kompozytowych.
