Abstract Scope Quenching and Partitioning (Q&P) steels are regarded as one of the promising candidates for 3rd generation advanced high strength steels (AHSSs) for their lean alloy elements and excellent mechanical properties. TS (tensile strength) × EL (Elongation) product of the Q&P steels can reach a value above 20000 GPa∙% and are qualified for the manufacture of anti-intrusion parts to reduce the body-in-white weight of vehicles and to increase the passenger safety. However, galvannealing of Q&P steels faces many challenges. One of the big challenges for Q&P steel galvanizing is the mechanical property degradation during galvannealing due to the harsh process parameters compared to the original Q&P heat cycle. The present work applied galvannealing heat cycle with various modified parameters on two grades of Q&P steel, studied the effect of galvannealing process on the tensile properties and microstructures of the Q&P steels and proposed an optimized galvannealing process for Q&P steels.
