Mechanical treatment of organic and inorganic solids has become extremaly important in materials science, chemical technology and various of other fields. However, quite recently researches have realized that the application of mechanical treatment as crushing, grinding, pulverization etc. to materials such as metals, rocks, minerals, creates wide range of intriguing effects e.g. generation of new physico-chemical properties, unusual phase transformations, formation of nanophases ect., thus wide range of new materials exhibiting attractive properties can be synthesised as well as novel material processing routes can be designed.
