Dear friends,
I'm working on 26MnB5 Hot rolled steel,micro analysis reveals the presence of C/Mn segregation along with the ferrite / pearlite bands.
I analysed the segregation area , segregation area predominantly has Mn and I also found Martensitic structure. (Image attached for reference)
I would like to understand if its only Mn or other alloying elements (say Ti) that would have led to formation of martensite even at a lesser cooling rate(curve shifts right).
what are the ways to overcome this issue ?
Ideas / comments / suggestions are welcome.
PS: Mn - wt% = 1.26%
Thanks,
Vinoth.
