The mechanism of γ-α Fe transformation and its impact on the morphological characteristics and basic mechanical properties of the ferritic steel is discussed. It is proposed to merge the categories: Widmanstštten ferrite, coarse acicular ferrite and both upper bainites into the new ′Widmanstštten bainite′ category. Change of the category name of acicular ferrite into ′intragranular bainite′ is suggested.
