摘要：

The transformation behavior and microstructural evolution of two alloys representing the extreme rich and lean compositional variations expected for production quantities of an ultralow-carbon (ULC) steel have been characterized. Dilatometry, optical microscopy, transmission electron microscopy (TEM), and microhardness measurements were used to identify the microstructures produced at various cooling rates and to develop continuous cooling transformation (CCT) diagrams for these ULC steels. It was demonstrated that the compositional variations expected from production heats made with current fabrication practices cause extensive variations in the transformation behavior, microstructure, and microhardness (as well as other mechanical properties) of these steels.
