第3代汽车钢的组织与性能调控技术董瀚1,曹文全1,时捷1,王存宇1,王毛球1,翁宇庆1(1.北京市钢研科技集团公司钢铁研究总院先进钢铁材料技术国家工程研究中心)摘 要:介绍了第3代汽车钢的基础研究与工业试制工作.对国内外高性能汽车钢进行了回顾总结,在以"多相(Multi-phase),亚稳(Meta-stable),多尺度(Multi-scale)"(简称M3)为特征的组织调控理论的指导下,提出了高强塑积第3代汽车钢的超细晶基体与亚稳相的组织调控思路,采用了新型中锰合金化和逆转变奥氏体(Austenite Re......
and impact ductility of 5CrNiMo steel using three different additions of RE La element is studied in this paper. The mechanical properties of 5CrNiMo steel with RE La additions are be compared with that of the 5CrNiMo steel on the same heat-treatment condition without RE La element addition. The results show that the strength. hardness and impact ductility of 5CrNiMo steel will be improved......
ductility is dominated by solute drag dislocation creep, and the major failure mechanism is cavity growth and interlinkage. Key words: AZ31 Mg alloy; solute-drag creep; tensile ductility; superplasticity... with casting Mg alloys, deformed Mg alloys offer higher strength and ductility, and better comprehensive mechanical properties which allow their extensive application in aerospace, transportation......

content for the ductile-to-brittle transition of Ti and does not degrade the ductility. Key words: oxygen; Ti-Zr alloys; ductility; powder metallurgy 1 Introduction Titanium (Ti) and its alloys have been widely studied for biomedical applications, due to their high specific strength, high corrosion resistance, and good biocompatibility. Commercially pure Ti has the best ductility, but can only......
