89A0052 Phase Transformation Unit of BainiticFerrite and Its Surface Relief in Low and MediumCarbon Alloy Steels The lath- or plate-shapedbainitic ferrite of low and medium carbon alloysteels consists of packets of ferrite sublathswhich are composed of many finer and regularferrite blocks. They are uniform shear growthunits of bainitic ferrite phase transformation.No carbide is precipitated from them. The bainiticθ-carbides are precipitated from γ-α interfaceor carbon-rich austenite. The mode of arrangement
