The article presents electron-beam sintering of composite cermets based on aluminum oxide and titanium. An electron beam generated by a forevacuum plasma electron source for sintering was used. The sintering samples were made from fine-grained powders and compressed by uniaxial pressing. It is shown that when heated to 1600 °C, a powder mixture with a ratio of aluminum oxide of 50% (wt.) and 50% titanium (wt.) large pores are formed in the sample. Measurements of the emission spectrum of the beam plasma formed above the surface of the irradiated sample showed the presence of aluminum. This may be due to the evaporation of these components during electron beam irradiation.
