The Use of Differential Thermal Analysis-Effluent Gas Analysis in Metallurgical Research Investigations

Differential thermal analysis-evolved gas analysis for the determination of carbide and nitride phases in steel

“…Since that time these methods have been used to qualitatively identify and quantitatively determine approximately 35 carbides, carbonitrides, and nitrides, some of which could not be identified by any other method (4-16). These procedures have also been used in studies of chemical methods used in the isolation of pure Fe3C from steel, (15), in studies showing changes in carbonitride composition with heat treatment (12,13), and to show the change in types of carbides and nitrides formed in steel as the heat treatment of the steel is changed (7,(9)(10)(11)(12). Such changes are important because the type of precipitate formed is known to have a profound effect on the mechanical properties of the steel.…”
