Abstract

Atomic absorption analysis has been used to study the impurity diffusion of copper in nickel in the temperature range between 1080 and 1613 K. The linear Arrhenius plot of the impurity diffusion coefficient of Cu in Ni has been expressed as follows:<BR>(This article is not displayable. Please see full text pdf.) <BR>\oindentAtomic absorption analysis is found to be useful to measure the penetration profile for the impurity diffusion in metals where suitable radioisotope as a tracer is unavailable or the half-life of radioisotope is very short.
