The book "Metastable, Mechanically Alloyed and Nanocrystalline Materials" (Proceedings of ISMANAM-2001) edited by E. Ma, M. Atzman, and C.C. Koch, is a comprehensive collection of 659 pages of research articles focusing on the use of miniature grinding mills to modify the constitution and structure of powdered materials, particularly for creating metastable or nanocrystalline materials. The proceedings, first published in two journals, have also been compiled into a single volume by Trans Tech Publications Ltd. The articles cover a range of topics, including the control of grinding severity, the formation of amorphous alloys, mechanochemical processes, and the synthesis and characterization of nanocrystalline materials. The research highlights the accessibility and cost-effectiveness of the equipment, making it a valuable resource for materials science researchers globally. The reviewer, Robert W. Cahn, notes that while the scientific interest in this field is significant, the engineering implications of the findings are less clear. The book is part of a broader trend of publications that contribute to the democratization of materials science research.The book "Metastable, Mechanically Alloyed and Nanocrystalline Materials" (Proceedings of ISMANAM-2001) edited by E.
