The results show that grains at core are coarser and deformation bands are observed at surface,while microstructure both at core and at surface is composed of bainitic ferrite laths with high dislocation density and interlath cementite or residual austenite.Good uniforinity in h...

结合NQP钢连续冷却时的相变特点，分析其截面硬度波动在±1.5HRC内的原因在于其有较好的贝氏体淬透性，模块整个截面上都得到了均匀的贝氏体组织，贝氏体板条宽度和位错密度的差异使得其表层硬度稍高于心部。

The microstructure, strength-toughness and fatigue properties of an ultrahigh strength steel 40CrMnSiMoVA have been investigated. The so-called eta-bainite,composed of thin rareined austenite films within or between the bainitic ferrite laths was found in the steel after isothermally quenched at 300℃ for 1h.

本文研究了飞机起落架用超高强度40CrMnSiMoVA钢的显微组织、强韧性和疲劳性能，结果表明，该钢经300℃等温1h淬火可获得由贝氏体铁素体板条与条间或条内的残余奥氏体薄膜所组成的准贝民体组织。

After tempering at 700℃, bainitic ferrite laths started to coarsen. The grain boundary characteristics and effective grain size of ULCB steels can be measured by EBSD technique.

晶界特征结果显示，轧态和回火态组织均存在大量低能量小角度晶界和低Σ值重位点阵晶界。

RPC steel and RQ steel are constituted by bainite and martensite microstructures before tempering. The microstructure of RPC steel did not change obviously except some bainitic laths coalescing were detected by means of SEM during tempering, while the boundary of bainitic laths of RQ steel disappeared quickly and finally formed polygonal ferrite forms accompanied a dramatic decrease in hardness.

回火前两种钢板组织均为贝氏体和马氏体的复合组织，经RPC处理后的钢板随回火温度的提高组织没有明显变化，只是一些板条出现合并现象，而经过RQ处理后的钢板随回火温度的升高板条很快消失最终演变成多边形铁素体，硬度也随之大幅度下降。

Tie-line and level-law calculations show that low-carbon ferrite nucleates and grows, leaving the remaining austenite richer in carbon.

由截线及杠杆定律分析可知，低碳铁素体成核并长大，剩下含碳量高的奥氏体。

Acicular ferrite microstructure in micro-alloyed steels, which nucleates around non-metallic inclusions, especially oxide inclusions, has high strength and good toughness and possesses strong grain-refining ability by itself. The ultra-fine grained steel with excellent weldability is likely to be produced by forming in materials a great number of fine and dispersive micro-inclusions which is helpful to induce AF to nucleate around them through oxide metallurgy technology.

微合金钢针状铁素体组织强度高、韧性好，在奥氏体晶内非金属夹杂物上诱导形核，具有很强的自身细化晶粒的能力，通过氧化物冶金技术控制钢铁材料形成大量细小、弥散，具有诱导AF形核能力的有益微夹杂物，有望获得焊接性能优良的超细晶粒钢。

This makes ZnFe2O4 a good candidate to be studied on the relationship between the cation occupancies and the preparation processes.NiZn ferrite is one of the most widely used spinel ferrites.

由于其具有高电阻率和高磁导率，在1 MHz以上的中高频应用中，是性能最好的软磁材料。

Increase with the slags TFe, the low melting point calcium ferrite increases.

随渣中TFe含量的增加，低熔点的铁酸钙增加。
