Zero-Flux Planes and Flux Reversals in Multicomponent Diffusion. Final Report

摘要

This progress report covers the fifth and final year of operation under Contract DE-AC02-81ER-10814. The principal area of research during the contract period has been interdiffusion in multicomponent alloys for the development of zero-flux planes and flux reversals, diffusion paths and diffusion structures, and analytical representation of diffusion paths for ternary, quaternary and quinary diffusion couples. The systems investigated are: Cu-Ni-Zn, Fe-Ni-Cr, Cu-Ni-Zn-Mn, Ni-Co-Cr-Mo and Ni-Co-Cr-Fe-Mo systems. A brief general review of the research contributions during the contract period is also given. During this final year of operation of the agreement, the research emphasis has been on the representation of diffusion paths for both single phase and two-phase diffusion couples with 3 to 5 components (three projects).
