摘要：

A phenomenological theory of domain growth in intermediate two-phase fields is proposed. Using it to interpret the divergent behavior of the thermal relaxation time of Cu3Au, one learns that the upper and lower portions of its coherent two-phase region acquire their temperature broadness from the stresses around edge dislocations and point defects, respectively. Similarly it is inferred that point defects act in the lower part of the semi-coherent two-phase field of Ni3Mn. It is noted that the crystal defects can also be identified through studies of domain development in samples quenched to Tc, the singular point of the thermal relaxation time. © 1978.
