摘要
针对第一代先进高强度钢塑性低与第二代先进高强度钢成本高、工艺性较差,国内外对第三代先进高强度钢开展了大量研究。通过对相关报道分析,第三代先进高强度钢是以高强度BCC结构为基体,在基体上有一定量的较高稳定性FCC结构的复合组织。对第三代先进高强度钢如δ-TRIP钢、DSHT工艺、纳米贝氏体钢、中锰TRIP钢、Q&P钢、HS-Q&P钢进行了介绍及展望。
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 S-TRIP steel, DSHT process, nanobainite steel, medium manganese TRIP steel, Q＆P steel, and hot stamping Q＆P steel.
