Abstract
Method for coding the granular structure of metallic powders, characterized in that the granulated starting material of any grain form is subjected to a milling in ball mills and oscillating rocking, with active additions of up to a maximum of 10% of the weight of the material to be ground, and for a period of up to 20 hours, preferably with additions of 0.1% and 5% and a grinding duration of 10 hours, with no change taking place, or only a very small average of the screening analysis primitive, however rising the volume of filling and shaking with respect to the starting powder.
