WebApr 1, 2024 · The influence of partitioning temperature on carbon partitioning during the quench and partition (Q&P) cycle and the associated non-equilibrium phase transformation thermodynamics have been investigated. Lower partitioning temperatures are reported to result in higher carbon partitioning with varying austenite phase fraction. WebThe thermal processing route to achieve this microstructural balance is consistent with a Quenching & Partitioning process (Figure 4). Both SHF980 and the reference DP980 are shown to have 660 MPa yield strength and 1000 MPa tensile strength. However, where DP980 has 15% elongation, SHF980 has 23% elongation.
