Strength And Ductility

Though more and more structural and safety automobile components are manufactured using hot stamping technology for the advantage of excellent shape accuracy while producing ultra high strength parts without any springback.Fewer hot stamping steels are developed except 22MnB5 steel, which exhibits ultra-high strength but limited ductility. Inspired by the application of quenching and partitioning C-Mn-Si steel, the microstructure and properties of a 30Cr13 steel subjected to quenching and partitioning treatment were studied to evaluate the possibility of martensitic stainless steel as alternative for hot stamping steel with high product of strength and ductility. The experiment result shows that, enhanced mechanical properties of Rel=1350MPa, Rm=1740MPa, and A=17.5% can be achieved through appropriate treatment. Due to the unique phase transformation conditions of martensitic stainless steel, processing parameters and corresponding equipments for automobile components manufacturing have to been investigated.

Quenching and partitioning (Q&P) treatment was applied to a commercial low carbon martensitic stainless steel, AISI Type 410 (Fe-12Cr-0.1C). The condition of partial quenching and partitioning was optimized with consideration of the untransformed austenite fraction and stability of austenite (carbon concentration in solid solution). As a result, the amount of retained austenite could be increased up to approximately 15 vol%. Tensile testing revealed that the specimens after Q&P heat treatment exhibited lower yield stress and larger work hardening rate compared with quench-and-tempered (Q&T) specimens under the same tensile strength level, resulting in a significantly better strength-ductility balance. It was confirmed that the TRIP effect had contributed to the mechanical property.
