Notes:
There have been several recent efforts to account for the broadening of the superstructure Bragg maxima and their displacements in reciprocal space observed for partially transformed b.c.c. solid solutions containing the ω phase. They have been concerned with intensity calculations from models for which the ω regions are defective in a variety of senses. All of the models include only one ω variant, while in fact the system must contain four equally likely variants. A method to correct the calculated intensity for interference effects among the variants, omitted from these models, is described. It is applied to a specimen model. Possible applications of the method are discussed. Though the concept is illustrated by its application to the ω phase, it is readily generalized to any multivariant system.
