THE DYNAMICS OF SOLID-SOLID PHASE-TRANSITIONS .2. INCOHERENT INTERFACES

Incoherent phase transitions are more difficult to treat than their co herent counterparts. The interface, which appears as a single surface in the deformed configuration, is represented in its undeformed state by a separate surface in each phase. This leads to a rich but detailed kinematics, one in which defects such as vacancies and dislocations a re generated by the moving interface. In this paper we develop a compl ete theory of incoherent phase transitions in the presence of deformat ion and mass transport, with phase interface structured by energy and stress. The final results are a complete set of interface conditions f or an evolving incoherent interface.
