Abstract
Using the method of transmission electron microscopy, we studied the microstructure evolution of the Ni75Mo20Al5 alloy at temperatures ranging from 600 to 1600 °C. It has been shown that above the temperature of the transition “ordering-phase separation” (1200-1300 °C) a phase separation process occurs in the Ni/Mo and Ni/Al diffusion pairs. Below the transition temperature the Mo3Al and Ni3Al phases are formed. At temperatures of 800 °C and below, high-dispersion particles of the Ni3Mo phase precipitate. The role of Al in the heat resistance of Ni-Mo system superalloys is discussed.
