چکیده:

Mechanochemical processes are discrete processes in which structural and chemical modifications occur at each impact loading or during subsequent relaxation[1, 2]. Different processes, such as crystallite size refinement and phase transformation, take place concomitantly and the amount of powder involved in each process at the impact is determined by the complex phenomena occurring on microscopic scale under the action of compressive and shear stresses
