FORMATION OF X-ray AMORPHOUS MATERIAL DURING MECHANICAL ACTIVATION (BY THE EXAMPLE OF NaCl)

摘要

A nonlinear elastoplastic model for collisions between solid particles was used to calculate the parameters of melting and solidification at an impact-friction compact between particles being ground in various grinding machines :ball mills ,disintegrators,and others. The mechanisms are comsidered for the formation of nanocrystalline particles and the chemical reactions accompanying solidification of thin melt layers under conditions when the local contact temperature varies at a high rate.
