摘要

就目前汽车行业新材料的研发和现有材料的优化趋势而言，最受关注的是可冲压性提高的渐进式高强度双相（DP）钢，它是为当前市场的特定内部车身部件设计的冷冲压。与目前的DP等级相比，新等级的DP钢提供了高强度和良好成形性的结合，并有助于车辆零件的重量节省10%至20%。由于其顶级性能，可成形性增强的DP钢可以用更少的钢材吸收更多的碰撞能量。结果，分析了第一代高强度DP780GI和DP780GI-HF材料（下文称为DP780GI-HF）。实验确定的DP钢和DP钢的成形极限曲线证明了DP钢的压模性能的提高。

EFFECT OF RETAINED AUSTENITE ON PLASTIC CHARACTERISTICS OF DUAL PHASE STEELS

In terms of the current trend of research and development of new materials and optimization of current materials in the automotive industry, the greatest attention is paid to progressive high-strength dual-phase (DP) steels with increased stampability, which are designed for cold stamping for specific internal car body components of the current market. New grades of DP steels provide a combination of high strength and good formability and contribute to the weight savings of vehicle parts by 10 to 20 %, compared to current DP grades. Thanks to their top properties, DP steels with increased formability can absorb more crash energy using less steel. As a result, high-strength DP780GI and DP780GI-HF materials of first generation (hereinfater DP780GI-HF) were analyzed. The stampability improvement of DP steels was demonstrated by the experimentally determined Forming Limit Curves for both steels.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
