Conclusions
-
1.
Two peaks were observed on the curves of plasticity vs testing temperature during heating and cooling.
-
2.
The maximum plasticity at 240o (cooling) is due to the initial stages of the martensitic γ→α transformation, and at 650o to the shift of the fracture mechanism (from intergranular to transcrystalline).
-
3.
The maximum plasticity at 600o (heating) is due to the initial stages of the reverse α→γ martensitic transformation, and at 740o to the development of recrystallization processes.
