【 摘 要 】

In the work, the effect the boron addition on the microstructure and properties of the composites with austenitic steel of matrix was investigated. The composites were consolidated using the high pressure-high temperature (HP-HT) method. Two composite types were fabricated, i.e. steel with 8 vol.% TiB2 and steel with 8 vol.% TiB2 and 1 vol.% boron. Density of sintered materials was measured according to the Archimedes principle. Mechanical properties were determined by Vickers microhardness and compression test. The wear resistance was investigeted using ball-on-disc method. The microstructure of composites was analyzed using a scanning electron microscope.
