NUCLEATION AND MIGRATION OF HIGH ANGLE GRAIN-BOUNDARIES IN BILAYER FOILS .1. NUCLEATION

Journal article

Thin evaporated epitaxial Cu/Ni bilayers were observed by transmission electron microscopy in order to study the modifications that occur to the initial structure during heating. Nucleation of mobile high angle grain boundaries was observed to occur from microtwins, which are present in the as-evaporated bilayers and are enlarged by reaction with the misfit dislocation arrays. A mechanism for this nucleation process is proposed and the significance of twins in the nucleation of mobile grain boundaries is discussed with reference to other work on the recrystallization of bulk materials. © 1980.
