METHOD FOR DIRECT SHAPING AND OPTIMIZATION OF THE MECHANICAL CHARACTERISTICS OF PERFORATING PROJECTILES IN HIGH-DENSITY TUNGSTEN ALLOYS

摘要

This invention relates to a process for direct shaping and optimization of the mechanical characteristics of perforating projectiles. /P P This process consists in implementing a blank of heavy ductile metal, having an axis of revolution, of mass volume at least equal to 17,000 kg / m ** 3 and is characterized in that said blank, roughly worked, is subjected to a working treatment at a temperature between ambient and 500 degree (s) C and according to a variable rate in a direction parallel to the axis of the blank. /P P This process finds its application in military munitions.
