Abstract Scope |
Precipitation above 950°C is a major ductility limiting factor in HSLA steel and poses concerns about quality and safety of steel during continuous casting processes. To study this phenomena, continuous casting simulation took place in a Gleeble 3500 followed by a detailed SAXS analysis of quenched microstructures. This analysis of precipitation characteristics and high temperature material properties will indicate how precipitation influences microstructure development and it limits ductility at high temperatures. A range of alloys containing Nb, V, N, and Ti were examined to evaluate various precipitate species and their development during high temperature processes in order to better understand how precipitate sizes and distributions can alter ductility behavior. |
