The Effect of Fe Content on the Microstructure and Tensile …
Furthermore, Figure 5 reveals that the welded joint possessing 0.3 wt.% Fe content displays the most refined weld surface. Conversely, a welded joint with 0.2 wt.% Fe content exhibits the coarsest surface morphology. Consequently, it can be deduced that the iron content serves as a crucial determinant in establishing the quality of the welded ...

Furthermore, according to Fig. 13 a, when the Fe content is constant, the wear rate increases with an increase in the applied load, but decreases as the Fe content increases at a constant load. This suggests that the Fe content has a significant impact on the volume and wear rate of the Ti-6Al-xFe tertiary alloy that has been ground and HIPed.

Ferrous iron content of intravenous iron formulations
As a fraction of the measured total iron, the measured Fe(II) content was <1 % for iron dextran and ferumoxytol, 1–2 % for ferric carboxymaltose and iron gluconate, and 10–15 % for iron sucrose. The Fe(II) content in iron sucrose was ≥7.5-fold higher than in any of the other IV iron formulations. Table 1.
