Purpose: The subject of the work was to study the effect of the sintering temperature on the properties and structure of TiB2-Al composites. Design/methodology/approach: TiB2-Al composites reinforced with 70 vol.% ceramic particles were prepared by powder metallurgy method. The high pressure - high temperature (HP-HT) method was employed to consolidate the sinters. Composites were sintered at pressure of 7.0 ± 0.2 GPa and temperatures of 520°C and 600°C. The duration of sintering was 60 seconds. In order to investigate the structure changes, the scanning electron microscope was applied. Young modulus measurements were carried out using ultrasonic method. Mechanical properties were determined by Vickers hardness tester. Findings: Two variants of TiB2-Al with respect to the sintering temperature (520°C and 600°C) were obtained by the HP-HT method. The application of the higher temperature of 600°C and pressure of 7.0 ± 0.2 GPa and time of 60 seconds permits to obtain the higher properties of this composites in comparison with the sinters which were obtained at 520°C. Practical implications: From a practical position it is important to optimize the sintering densification of TiB2-Al composites by high pressure -high temperature (HP-HT) method. Originality/value: The results from this work can be useful in determining conditions for sintering the materials with the high amount of titanium diboride.
