1·Pipeline steel adopting the spicular ferrite owns the better properties of forming.
采用针状铁素体的管线钢具有较好的成形性能。
2·At high temperatures, the material is entirely austenite, but upon cooling enters a region where the stable phases are ferrite and austenite.
在较高温度时，这种材料全部是奥氏体，但随着冷却就进入到铁素体和奥氏体稳定状态的区域。
3·Since this chemical separation of the carbon component occurs entirely in the solid state, the resulting structure is a fine mechanical mixture of ferrite and cementite.
由于这种碳成分的化学分离完全发生在固态中，产生的组织结构是一种细致的铁素体与渗碳体的机械混合物。
4·The results show that the addition of Zr increases the content of acicular ferrite and improves the microstructure of weld metal.
结果表明，锆的加入增加了焊缝金属中针状铁素体的含量，改善了焊缝金属的微观组织。
5·Control of this reaction, which arises due to the drastically different carbon solubility of austenite and ferrite, enables a wide range of properties to be achieved through heat treatment.
控制这一由于奥氏体和铁素体的碳溶解性完全不同而产生的反应，使得通过热处理能获得很大范围的特性。
