Abstract

Our understanding of the disordering, partial or complete, of B2 intermetallics during intense milling is reviewed choosing, in particular, the FeAl intermetallic as an example, and making especial effort to interpret the changes occurring in terms of the deformation mechanisms operating during milling and the crystalline and structural changes produced. The ease of disordering can be correlated with the relative energies of the possible point defects produced during milling, or by the corresponding types of active dislocation. Attempts at modelling the structural changes produced by such intense deformation appear to be in good agreement with detailed structural analyses that have been carried out. Many aspects of the processes occurring are still poorly understood, however, and there remains scope for further investigation.
