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.
