綜述了國(guó)內(nèi)外對(duì)于低合金高強(qiáng)鋼(HSLA，High Strength Low Alloy)焊縫金屬中針狀鐵素體(AF，Acicular Ferrite)的最新研究進(jìn)展得出，要想獲得較多的AF，主要從3個(gè)方面加以有效控制：① 合金元素中含005%~010% C，且C當(dāng)量小于039，合理控制Mn，Ni，Ti，B之間的相互比例，保持硼氮比(B/N)在06~08之間，鋁氧比(Al/O)在043~073之間，降低N，S，P含量；② 夾雜物尺寸為05~08 μm，表面富10~20 nm TiO薄層且呈球形，促使生成更多的第Ⅲ、Ⅳ類夾雜物；③ 較低熱輸入(HI， Heat Input)時(shí)合金元素?zé)龘p較少，冷卻速率較快，焊縫組織得以細(xì)化。

This paper reviews the newest worldwide research progress on acicular ferrite (AF) in weld metal for high strength low alloy (HSLA) steel. More AF can be mainly obtained by the effective control of three aspects: ① when C content is between 005 and 010% with a carbon equivalent of less than 039, the ratios between Mn, Ni, Ti, and B can be reasonably controlled, and the ratio of B/N is between 06 and 08, Al/O is between 043 and 073, while N, S, P contents are reduced; ② when the size of inclusion is in the range of 05~08 μm with 10~20 nm TiO in the inclusion surface and with its shape being globular, then more third and fourth types of inclusions can be obtained;
