摘要：

The study focused on the transformation of body-centered cubic (BCC) phase presented in the sandwich morphology of intergranular oxide layers in an austenitic steel. The polycrystalline BCC phase, characterized by a random orientation to the matrix, does not arise from the commonly accepted martensitic transformation but rather from a massive transformation. Through experimental design, it is conformed that the sandwich morphology along the grain boundaries is attributed to thermal fatigue.
