Impurity diffusion of Al in γ-Fe has been studied by using non-radioactive tracer Al. Penetration profiles have been determined by the glow discharge spectroscopy measurement. Penetration curves obtained have been good for the diffusion analysis. The glow discharge spectroscopy measurement 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. It is found that the impurity diffusion coefficient of Al in γ-Fe is about one order smaller than that of self diffusion.
