Intragranular ferrite morphologies in medium carbon vanadium-microalloyed steel
The aim of this work was to determine TTT diagram of medium carbon V-N micro-alloyed steel with emphasis on the development of intragranular ferrite morphologies. The isothermal treatment was carried out at 350, 400, 450, 500, 550 and 600°C. These treatments were interrupted at different ti...

| description | The aim of this work was to determine TTT diagram of medium carbon V-N
micro-alloyed steel with emphasis on the development of intragranular ferrite
morphologies. The isothermal treatment was carried out at 350, 400, 450, 500,
550 and 600°C. These treatments were interrupted at different times in order
to analyze the evolution of the microstructure. Metallographic evaluation was
done using optical and scanning electron microscopy (SEM). The results show
that at high temperatures (≥ 500°C) polygonal intragranulary nucleated
ferrite idiomorphs, combined with grain boundary ferrite and pearlite were
produced and followed by an incomplete transformation phenomenon. At
intermediate temperatures (450, 500°C) an interloced acicular ferrite (AF)
microstructure is produced, and at low temperatures (400, 350°C) the sheave
of parallel acicular ferrite plates, similar to bainitic sheaves but
intragranularly nucleated were observed. In addition to sheaf type acicular
ferrite, the grain boundary nucleated bainitic sheaves are observed.
