Abstract: 
Microstructure of the dental alloy Ni-Cr-Mo (Rodent) after casting in the vacuum-pressure furnace has been examined. Chemical analysis by using energy dispersive spectroscopy as well as crystallographic orientations topography by using backscattered electron diffraction in the scanning electron microscope was carried out. It was found that after casting the microstructure consists of dendrites of solid-solution strengthened nickel–chromium matrix (γ phase). Inside the dendrites the precipitations of molybdenum silicides, eutectics γ–P and few particles of aluminum oxide were observed.
