Abstract
This paper describes the optimal modes of initiation of self-propagating high-temperature synthesis with the help of electron beam on the example of a Ti–Al–C powder mixture. A pulsed electron beam with a particle energy of tens of kiloelectronvolts and a duration of hundreds of microseconds is used. Morphology, structure, and elemental composition of formed products in the form of Ti3AlC2 and TiC are studied.
