第一个证据是贝氏体铁氧体中存在一个四边形或稍微正交的晶胞。它支持了一种假设，即在与奥氏体接触的铁素体中存在的过量碳是由于传统立方晶胞对称性的改变而增加溶解度的结果。由于碳在铁氧体中的溶解度增加，与立方电池的偏差在高温下保持不变。
The first evidence is provided for the existence of a tetragonal or slightly orthorhombic unit cell of bainitic ferrite. It supports the hypothesis that the excess carbon that persists in the ferrite, which is in contact with austenite, is a consequence of an increased solubility due to the change in symmetry from the conventional cubic unit cell. The deviations from the cubic cell are maintained to elevated temperatures, as expected from an increased solubility of carbon in the ferrite.
