(MoNb)Si2materials were prepared using combustion synthesis and the vacuum hot-pressing technology. Cracks were introduced on the surface of polished materials using the Vickers indentation method. The crack-healing behaviour of (MoNb)Si2materials were investigated with high-temperature oxidation in air. The results show that after annealing at 900 °C, 1200 °C and 1500 °C for 1 h, the crack-healing behaviour was observed in each case. The bending strength obviously decreased when the cracks were introduced, and the materials significantly recovered after the heat treatment. The crack-healed samples exhibited higher bending strengths than the original level after the 1200 °C treatment, e.g. 479 MPa versus 195 MPa of pure MoSi2. MoSi2micro alloyed with niobium shows a high bending strength at room temperature and excellent crack-healing properties at high temperatures.
