Mg17Al12Intermetallic Prepared by Bulk Mechanical Alloying

In a last decade, nano-crystallized or amorphous materials are widely investigated. Such materials provide other directions for solving several issues in the field of materials science. Ball milling processes are general tools for preparing the nano-crystallized or amorphous material. The samples, however, show the fine powder-form and the most of those are very sensitive against circumstance around. The bulk-form samples are desirable. The present work proposes the newly developed bulk mechanical alloying (BMA) technique as an alternative method for the ball milling. Successful solid-state reaction and the formation of nano-scale crystalline of Mg17Al17 phase will be demonstrated.
