Application of optical emission source developments in metallurgical analysis

Abstract

Recent developments in metallurgical analysis, which have potential for use in industry, are described. The paper concentrates on three techniques : firstly the use of pulse distribution analysis in spark-source optical emission spectroscopy to determine soluble aluminium in steel separately from the aluminium that is present as inclusions in the steel matrix; secondly, glow discharge spectroiiietry for the determination of alloying elements in steel, a technique which has potential for both bulk and surface analysis of steel, and lastly, inductively coupled plasma spectrometry. Data are presented, together with reproducibility measurements, which give the optimum conditions for niultielenient analysis of stccl using this technique.

Ferrous analysis

“…A recent review of developments in the ferrous metals industry focuses on the use of pulse height distribution analysis in spark source optical emission spectrometry, glow discharge spectrometry, and inductively coupled plasma spectrometry (185). The same topics are covered in another comparitive review published by a German group (247).…”
