“…In the present study, we investigate the production of ferritic steel alloys by the processing technology of direct strip casting (DSC). During DSC, the strip is subjected to extremely high cooling rates, and this is known to produce unusual microstructures and non-equilibrium behaviours (Shiang & Wray, 1991;Guillet et al, 1996;Mukunthan et al, 2000;Ferry, 2006;Dorin et al, 2015Dorin et al, , 2016. One of the most interesting findings has been the refinement of manganese sulfides (MnS) to the nanoscale size range and the suggestion that S may be retained in solid solution after DSC (Malekjani et al, 2013).…”

Complex precipitation phenomena in strip cast steels with high sulfur and copper contents

A series of three steel alloys with increasing Cu and S concentrations has been prepared by simulated direct strip casting. It was found that the rapid solidification that occurs during direct strip casting results in the formation of a high number density of fine MnS precipitates, while Cu was retained in solid solution above equilibrium concentration. Upon ageing the MnS particles were found to coarsen and increase in volume fraction, indicating that some S was retained in solid solution in the as‐cast condition. Ageing also resulted in the precipitation of Cu‐rich precipitates. A new method to determine precipitate composition from small‐angle neutron scattering is presented. This methodology, in conjunction with atom‐probe tomography, has been used to show that the composition of the Cu‐rich precipitates depends on the alloy's bulk Cu content.

“…1) Phosphorus is one of the major impurities in the process of iron smelting, since segregated phosphorus causes low toughness and poor weldability. Near net shape casting [2][3][4][5] such as twin drum type strip continuous casting [6][7][8] and thin slab continuous casting is the most promising process for developing a fine dispersion of micro-segregations due to rapid solidification. The strip casting can save about 90% of the energy for the process from casting to hot rolling.…”

Influence of Phosphorus Micro-Segregation on Ferrite Structure in Cast Strips of 0.1 mass% C Steel

Cast strips of 0.1 mass% C steel with or without phosphorus addition have been characterized by electron back-scattering diffraction pattern (EBSP) measurements. Then the formation of globular ferrite structure was discussed. EBSP analysis combined with optical microscopy clearly showed that a globular grain was fitted to be an -ferrite grain. The EBSP analysis suggested that the retained-grain grew predominantly in the -grain and formed the globular -ferrite during cooling. The microtexture in the globular ferrite structure depended highly on the solidification structure. It is important to scatter the primary dendrite growth direction into neighboring areas to develop fine prior-and structures for the cast strip of high-phosphorus steel.
