Abstract

Morphology of precipitates in the Cu-Cr-Ti alloys has been investigated using scanning electron microscope and transmission electron microscope in the present work. It has been found that there exist precipitates with two different morphology—spherical and cubic. Misfits between matrix and different precipitates have been determined using high resolution transmission electron microscope images. Interfacial energy and elastic strain energy have been calculated quantitatively. Tendency of morphology of precipitates has been explained by comparing the interfacial energy and elastic strain energy.
