Abstract

We have analyzed the physical processes in a vacuum chamber in the centrifugal dispersion of blanks of D16 and AMg6 aluminum blanks rotating at a rate of 10–80 m/sec with local melting under the action of a stationary electron beam of power density ∼109 W/ m2. A method for approximate calculations of melting under flash heating, diffusion, and vapor and gas release into vacuum is proposed.
