ACICULAR FERRITE. A highly substructed nonequaixed ferrite formed upon continuous cooling by a mixed diffusion and shear mode of transformation that begins at a temperature slightly higher than the transformation temperature range for upper bainite in that it has a limited amount of carbon available; thus, there is only a small amount of carbide present.
