Mechanically milled nanocrystalline cubic titanium trialuminide and iron aluminide intermetallics

Journal Article


Abstract


  • This paper is an overview of the authors' recent studies involving ball milling of cubic intermetallics using controlled ball motion to induce a low energy shear mode of ball/particle interaction during milling. Two intermetallics have been studied: Mn-stabilized cubic titanium trialuminide (L12 Al3Ti(Mn)) and the ordered body centred cubic B2 Fe-45at%Al iron aluminide. The microstructural evolution involving the formation of nanocrystals, mechanical disordering and variations in the lattice constant with increasing milling time are discussed for both intermetallics.
