Ti Content

The influence of Ti/N ratio on the effective boron and mechanical properties was investigated by analyzing data from low carbon boron alloyed bainitic steel plates. The result shows Ti/N ratio varies with effective boron value. Less than 50% effective boron was obtained when Ti/N ratio is below 3.3, nearly 90% effective boron is obtained when ratio Ti/N is more than 4; Adding enough Titanium is an effective and economic way to improve qualified ratio of bainitic steel plate. The Ti content between 0.010% and 0.030% does not have obvious effect on the toughness of the bainitic steel;

Partitioning Time

A low carbon steel was treated by quenching and partitioning (Q&P) process, and a detailed characterization of the microstructural evolution and testing of mechanical properties were carried out. The resulted mechanical properties indicate that with the partitioning time increasing, the tensile strength decreases rapidly first and then remains stable, and the total elongation increases first then decreases. The investigated steel subjected to Q&P process exhibits excellent products of strength and elongation (17.8-20.6 GPa•%). The microstructural evolution of martensite matrix during the partitioning step was observed, and the morphology and content of retained austenite were characterized. The working hardening behavior of the samples was analyzed, and the retained austenite with higher carbon content contributes to the uniform elongation more effectively.
