The Development of the Structure, Morphology, and Fractional Composition of “Al−2B” Composite Powders in the Course of Mechanical Activation

  • 2 Accesses

Abstract

The evolution of the structure-related morphological characteristics and fractional composition of an “Al–2B” composite powder has been studied in the course of the synthesis by the mechanical alloying method. The internal stresses, specific interface areas, and statistical characteristics of fractional composition have been determined as depending on the duration of powdered mixture treatment. Mechanisms for development of the composition and structure of the composite powder are discussed.
