First-order phase transformations, as typified by the                      martensite reaction, are being examined.    The interrelation of                discrete dislocation and nonlinear continuum diffuse interface                  models of interfacial core structure is investigated                            theoretically and experimentally in model martensitic systems.  A               nonlinear nonlocal continuum theory explores the competition                    between nucleation and continuous modulation modes of first-order               transformations.  Transmission electron microscopy investigation                of ferrite interfaces assists in defining the interfacial                       structure.  Homogeneous nucleation experiments are performed in                 submicron austenitic particles, using high magnetic fields to                   supply additional thermodynamic driving force.
