In this work, AlMgB14-TiB2 composite materials were obtained by thermochemical-coupled self-propagating high-temperature synthesis (SHS) and subsequent spark plasma sintering. The phase composition of the raw powder mixture, the obtained SHS product, and the sintered sample was determined. The main phase in the obtained SHS product and the sintered sample is TiB2. The structure of the sample is not uniform. Large TiB2 agglomerates were found. The hardness of the obtained sample is 26.1 GPa.
