Abstract
The fundamentals of quenching and partitioning process are discussed including various points of view and existing different approaches. Evolution of structure is considered including effect of processing parameters (quenching temperature, temperature, and duration of partitioning) and contribution of bainite reaction. The role of retained austenite stability and possible impacts of various factors are presented. The chapter includes the discussion of relationship between microstructure and the main properties of Q&P steels such as the combination of strength and ductility, strain hardening, and hole extension, as well as appropriate influence of steel composition. Modern modifications of Q&P thermal cycle are presented.
