Abstract
A comprehensive metallographic study of coarsening in the (γ 1 + γ 2) region of the Cu-Ni-Cr system in reported. Particles of γ 2 form and coarsen at the extreme Cu rich side but all the other alloy compositions form interconnected structures arising from spinodal decomposition. These are shown to coarsen by increasing their uniform interphase spacings. It is argued that this involves some diffusion controlling interaction between adjacent arms of the structure in which the phases move bodily. Subsequent stages involve the break up into particles, increasing the interface area and finally particle coarsening and incoherency. Rates of all stages have been measured. A comprehensive coarsening sequence is proposed for different modes of development for such initially interconnected spinoda´l structures.
