Abstract : The crystallography of the martensitic transformation in the Fe-30 Ni alloy was reinvestigated. The scatter in the habit plane as determined from measurements on the mid-rib plane was smaller than reported previously, and the orientation relationship was determined from a martensitic plate having known direction cosines. From agreement with crystallographic theory and from observations of the morphology of the martensite plates, it is suggested that the mid-rib plane represents the starting region of the transformation.
