Effects of annealing treatment on the microstructure and mechanical properties of the AlN-SiC-TiB2 ceramic composites prepared by SHS-HIP

► The annealing treatments for the AlN-SiC-TiB2 ceramics were carried out. ► The annealing treatment is beneficial for improving the mechanical properties. ► The desolution of SiC-rich solid solution and precipitation of fine TiB2 grains occurred.
