In the decades after the discovery of the Portevin-Le Chatelier effect, much attention was paid to defining the various types of serrations which appear under different test-temperature or strain-rate conditions. Such efforts were almost exclusively restricted to describing the features of stress-strain curves of f.c.c. alloys. Reports on serration types and their properties in b.c.c. alloy systems are rare and, when they exist, lacking in detail. Serrations appearing in tests with steels have apparently been considered as rather irregular and, therefore, inaccessible for a systematic evaluation. This paper is the first to report on the author's results for a low-carbon steel. It will demonstrate that almost all of the features of serrated flow, which have in the past been found in substitutional alloys, are equally well exhibited in an interstitial alloy.
