Microstructure of Continuous Cooled Niobium Steels

  • Najma Shams
Material Research Summary


This study investigates the transformation behavior and microstructural variations through cooling rates for C-Mn steels with different niobium contents. The ferrite produced at low niobium concentration is quite different from that produced by increasing niobium concentration. The transformation temperature in carbon manganese steels containing niobium is strongly dependent on both the niobium taken into solution and the cooling rate. The maximum depression in transformation temperature is produced by an optimum amount of niobium. This is determined by steel chemistry, particularly the interstitial content of the steel.
