Based on the low plasticity of the first generation advanced high strength steel (AHSS) and high cost with poor technological properties of the second generation AHSS, a lot of research works were done about the third generation AHSS at home and abroad last decade. Through analyzing the related research reports, the third generation AHSS is a composite microstructure with high strength BCC for the matrix that contain a certain amount of higher stability of FCC. Introduce and prospects are conducted about the present research of the third generation AHSS such as δ-TRIP steel, DSHT process, nanobainite steel, medium manganese TRIP steel, Q&P steel, and hot stamping Q&P steel. ©, 2015, Chinese Mechanical Engineering Society of Heat Treatment.

The influence of carbon, trace niobium and annealing temperature on mechanical properties and microstructure of dual-phase steel were studied by ULVAC-CCT-AY-II continuous annealing simulator. The results show that carbon and niobium have little influence on phase-transition temperature, but can reduce the martensite content at 760℃ annealing. The microstructure is obviously refined by trace niobium addition, and recovery structure is more likely to be formed when annealing temperature is under 780℃. Pearlite is easily formed in the steel with higher carbon content when annealing temperature is above 800℃. Furthermore the yield strength and tensile strength are increased by the addition of carbon and niobium. The strength is improved with niobium dual phase steel, and the elongation is also higher than the steel without niobium addition. When annealing temperature is at 820℃, the niobium micro-alloyed dual-phase steel can achieve a good comprehensive mechanical properties. ©, 2015, Chinese Mechanical Engineering Society of Heat Treatment.
