Abstract

The transformation from high to low troilite occurs via a transitional structure. The transformation to this transitional state is continuous, whereas that to the low-temperature form is discontinuous. This illustrates alternative metastable behavior in a system when nucleation of the low-temperature phase may be impeded.
