Abstract

Recent research on the structure and properties of intermetallic compounds processed by ball milling—i.e. mechanical attrition—is reviewed. Mechanical attrition includes synthesis of intermetallics from the elemental powders of their constituents (mechanical alloying) and from milling the compound powder (mechanical milling) to provide changes in structure and/or microstructure. Mechanical attrition has been used to synthesize intermetallic compound compositions for a variety of reasons: for example (1) materials difficult to produce by conventional solidification because of phase equilibria constraints; (2) introduction of unique microstructures to enhance certain properties, and (3) formation of metastable structures at intermetallic compositions. The properties of intermetallics modified by the structures/microstructures induced by mechanical attrition include mechanical behavior, hard magnetic behavior, hydrogen storage, and catalysis. In addition the extensive plastic deformation observed by TEM in milled nominally brittle intermetallics may offer a means of studying deformation behavior in very brittle intermetallics at essentially ambient temperature.
