Abstract
This paper offers a bird’s-eye view of the whole subject-matter of the Workshop. — The relation of the kinetics of the establishment of long-range order to the nature of thermal treatment and to the ordering energy is briefly reviewed, and some current issues highlighted. Some matters relating to the measurement of order and to the role of antiphase boundaries are discussed. — Disordering by means of intense cold-work, with special reference to ball-milling, is examined. Thermal disordering, by annealing above T c , is compared with the aforementioned processes; there is evidence that thermal disordering is preferentially catalysed at antiphase domain boundaries. It is not known whether this also true for the alternative processes. The question is finally addressed whether an alloy partially disordered by mechanical deformation is in a different state from one partially ordered, to the same value of the LRO parameter S, by annealing an initially thermally disordered alloy.
