Özet

Microsegregation of manganese through secondary dendrite arms during solidification of ternary Fe - 1.6% Mn - 0.8% C steel was investigated in quenched unidirectionally solidified specimens. The microprobe analysis of these specimens showed that secondary dendrite arms solidified to produce asymmetric distribution profiles (saw tooth or TGZM effect). It is found that this effect can be one of reasons for the disappearance of secondary arms at the end of the solidification at low cooling rates and also for low segregation between secondary dendrite arms at high cooling rates.
