On the influence of phase transformations in a metal matrix of composite materials upon mechanical alloying during the disintegration of agglomerates of nanodiamond reinforcing particles

Resumo

The disintegration of agglomerates of nanodiamond reinforcing particles in a metal matrix upon mechanical alloying is studied. This process is shown to be influenced by phase transformations in the matrix. A hypothesis is suggested that the disintegration is a result of additional microstresses and microstrains arising in local domains due to variations in the density and molar (gram-atom) volumes of phases and parameters of the metal lattice upon phase transformations.
