Dynamics of Solid-Solid Phase Transitions 2. Incoherent Interfaces

摘要

Incoherent phase transitions are more difficult to treat than their coherentcounterparts. 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 are generated by the moving interface. In this paper we develop a complete history of incoherent phase transitions in the presence of deformation and mass transport, with phase interface structured by energy and stress. The final results are a complete set of interface conditions for an evolving incoherent interface. (AN).
