Abstract

An analytical potentiality of a glow excitation for elements in some binary alloys was studied in comparison with a high voltage spark discharge. The alloys adopted were Al-Si, Al-Ni and Fe-C alloys. With these alloys the linear relationship between the concentration ratio and the light intensity ratio of alloying elements was obtained except for the hyper eutectic phase of Al-Si alloys.
