On-Site Speaker (Planned) Alyssa Stubbers
Abstract Scope The connection between alloy content and high-temperature ductility behavior of steels is due to the inhibition of diffusion and precipitate formation caused by additional material present in alloys. This diffusion and precipitation behavior can cause low ductility regions to occur during crucial operations of a continuous casting process which may cause transverse cracking or total breakouts of steel. In this study, a range of alloys containing Nb, V, N, and Ti were examined to identify and characterize the influence of alloying elements on ductility behavior at temperatures above 700C. Using a Gleeble 3500, samples were hot tensile tested and quenched at failure for subsequent analysis using SEM and TEM techniques to evaluate ferrite to austenite phase transformations and precipitate formation. Ductility profiles and microstructural information were then used to construct a clearer picture of how alloying elements interact within the steel microstructure to modify high-temperature material properties.
