Phase Transformation Near Dislocations and Cracks

Abstract:

A generic model for nucleation of oriented second-phase in alloys in the vicinity of cracksand dislocations, is considered. The model employs the Ginsburg-Landau approach, which accountsfor the elasticity of crystalline solid and the interaction of structure/composition with the elastic ﬁeldin the vicinity of the defect and in the crystalline bulk. We examine the nature of the structural phasetransition and construct its phase diagram.
