Between 1911 and 1914, the Royal Aircraft Factory used the F.E.2 ("Farman Experimental 2") designation for three quite different aircraft that shared only a common "Farman" pusher biplane layout. The third "F.E.2" type was operated as a day and night bomber and fighter by the Royal Flying Corps during the First World War.

2008年5月1日 · In this paper, the stability, electronic and mechanical properties of three polymorphs of Fe 2 B were studied using CASTEP code. The calculated binding energy and formation energy values showed that Tp 2 (Space group, I 4 2 m) and Tp 3 (Space group, I 4 / mcm) structures of Fe 2 B are more stable than Tp 1 (I 4 2 m).

2022年9月15日 · Iron Boride (Fe 2B) has significant potential to be used as a wear- and corrosion-resistant ceramic because of its high hardness, good corrosion resistance, and low cost. However, the toughness and elastic heat resistance of Fe2B can be further improved under high-temperature wear conditions.

2021年2月15日 · In boride ceramics, Fe 2 B typically functions as the primary wear-resistant phase owing to its high hardness, but the elastic and ductile-brittle properties of Fe 2 B greatly influence its wear resistance and industrial application.

2014年6月11日 · Cr置换固溶Fe原子后， B-B键的键能可以由 5.6574 kJ/mol增大到 79.0047 kJ/mol，Fe2B中弱键键能的显著增强使得其内部的固有裂纹明显减少， 通过分析断裂面的晶体学取向， 发现试样Fe-8.8B倾向于沿{110}晶面族进行解理， 而Fe-8.8B中添加Cr后， 试样沿着(110)面发生断裂需要 ...

2023年4月20日 · The experimental studies show that the Fe2B alloy has a large magnetization (173 Am2/kg), a large Curie temperature (1017 K) and a relatively large anisotropy constant K1 (−0.80 MJ/m3), but the alloy is inappropriate for permanent magnet applications due to in-plane easy magnetization axis (EMD).

Fe2B crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Fe is bonded in a 4-coordinate geometry to four equivalent B atoms. All Fe–B bond lengths are 2.15 Å. B is bonded in a body-centered cubic geometry to eight equivalent Fe atoms.

2014年6月9日 · 河北工业大学硕士学位论文 i Fe2B 相在 Fe 基合金中性质及改性的研究 摘要 在寻找耐锌液腐蚀材料的大量研究试验过程中， 发现 Fe2B 作为耐熔锌腐蚀的铁基渗硼层或者耐锌液腐蚀的 Fe－B 合金中的一相， 起着主要的抵挡锌液腐蚀的作用。

2013年4月9日 · In this paper, the stability, electronic and mechanical properties of three polymorphs of Fe2B were studied using CASTEP code. The calculated binding energy and formation energy values showed...
