Abstract
A process for producing metal metalmetalloid powder, with its particles having ultramicrocrystalline structures to nanocrystalline structures with the metalmetalloid component being composed of at least one metal reacted with at least one metalloid of the group including C, N, O, H, B, and Si. The metalloids, C, N, O, H, B, and Si are introduced in a highly reactive form together with powders of the metals of the matrix metal and of the metals of the metalmetalloid component into a high energy mill to produce a metal-metalmetalloid powder with its particles having a ultramicrocrystalline to nanocrystalline structure both in the metal matrix and in the metal metalloid component.
