3rdGeneration Advanced High Strength Steel (AHSS) is a high alloy steel rich in manganese with promising properties for use in the automobile industry. The specific strength and specific toughness of these alloys is more favourable than traditional steels, allowing for lighter weight vehicles with lower emissions.
The present study investigates a novel method of manganese addition to steel through reductive alloying of manganese oxide in slag using silicon or carbon as reductants.
Argon oxygen decarburization (AOD) is the primary process to produce stainless steel which is also used for the processing of high manganese steels. In this study, the kinetics of decarburization and manganese losses of Fe-(5-25%)Mn-(0.6-2%)C melts was investigated by bubbling a mixture of Ar+O2 gas through a submerged nozzle at 1600. The influence of experimental variables such as gas flow rate and Ar/O2 ratio were determined.
The demand for new lightweight material in automotive industries is increasing recently. This phenomenon motivates the steelmaker to improve their steel specification. In order to make a good clean high manganese steel, inclusion type, morphology, size, and distribution can act as some parameters to specify a clean steel. The effect of alloying elements on the formation and modification of inclusions during the refining of high manganese steel production is the main objective of this work.
