Patent ID: 7028525

Claim:
A method for adiabatic deformation of a material body ( 1 ), comprising the steps of conveying a stamping member ( 2 ) towards the material body ( 1 ) such that the stamping member ( 2 ) impacts (F) the material body ( 1 ) with such velocity to generate adiabatic coalescence causing permanent deformation of the material body ( 1 ) and generating a rebound motion of the stamping member ( 2 ), and counteracting ( 3 ) the rebound motion of the stamping member ( 2 ) and generating at least one additional impact of the stamping member ( 2 ) against the material body ( 1 ), within a period during which kinetic energy of a reciprocating wave in the material body ( 1 ), generated in connection with the rebound motion of the stamping member ( 2 ), generates additional deformation in the material body ( 1 ) by gradual activation of sliding planes or mutual displacement of powder grains in the material body ( 1 ).
