Characterization and modeling of mechanical behavior of quenching and partitioning steels

Q&P annealing was applied to cold rolled carbon–manganese steel with Si. Q&P cycles with different partitioning temperature and time were simulated and the evolution of microstructure and mechanical properties was investigated. All the microstructures were composed of three constituents: partitioned martensite, laths of retained austenite and MA islands. Fine microstructure characterization confirmed that C diffusion plays an important role for …
