Transformation Induced Plasticity (TRIP) of SAE 52100 Steel during Martensitic and Bainitic Transformations


Transformation induced plasticity (TRIP) of SAE 52100 steel during quenching is investigated both experimentally and theoretically. TRIP parameter (K) is determined experimentally for both martensitic and bainitic transformations by using the stressed dilatometry technique. A new method for extraction of for an incomplete transformation is suggested for the martensitic transformation. Theoretical calculations using well established models for the TRIP effect and the results from the literature are used for the justification of the results of this work. The results for bainitic transformation is found to be in good agreement with both the literature and theoretical calculations using Leblond model. On the other hand, experimentally determined value is found to be significantly different from the literature. Nevertheless, it is still in reasonable agreement with the calculations using Leblond model.
