The microstructure of high manganese TWIP steels produced via simulated direct strip casting
Three TWIP steels based on the composition Fe-23Mn-3Si-3.3Al with different carbon concen�trations were examined. The alloys were produced by rapid solidification in an experimental apparatus designed to simulate direct strip casting conditions. Examination of the driving force for solidification...

| description | Three TWIP steels based on the composition Fe-23Mn-3Si-3.3Al with different carbon concen�trations were examined. The alloys were produced by rapid solidification in an experimental
apparatus designed to simulate direct strip casting conditions. Examination of the driving force
for solidification for this alloy showed the preference for BCC and FCC solidification were very
close for this composition, within 10% of one another. This factor combined with the high under�cooling resulted in the change in the primary solidified phase. Chemical analysis of the as-cast
strip showed inter-dendritic segregation of Si and Al, but negligible segregation of Mn. A simple
heat treatment was sufficient to chemically homogenise all alloys and produce microstructures
comprising a fully austenitic structure, consistent with thermodynamic predictions. |
