N2 - In situ ultrahigh-temperature XRD measurement of a MoSiBTiC alloy was carried out using a laser-heated diamond anvil cell and synchrotron radiation. This technique revealed the complicated dynamic behavior of phase transitions in the MoSiBTiC alloy on heating above 1950 °C. The MoSiBTiC alloy initially consisted of Mo solid solution (Moss), Mo5B2Si (T2), TiC, Mo2B, Mo3Si, and Mo2C phases. The Mo2B, Mo3Si, and Mo2C phases disappeared on heating at ~1647 °C. The Moss grains coarsened during heating and the Moss, TiC, and T2 phases were present >1950 °C. The obtained results verified the solidification pathway of the MoSiBTiC alloy.
