other four different phases exist in the alloy: at area A (a dispersed particle) or B (the iron-based matrix), the chemical composition is dominated by Fe. The contributions of W, Mo, Cr and V are also... phases in the iron-based matrix is favorable to improve the high temperature performance of the material.

of replaceable anode materials [2,3]. Iron-based oxides (α-Fe2O3) have attracted intensive research attention due to their higher theoretical specific capacity (1005 mA·h/g) [4]. However, the poor electrical conductivity and other drawbacks prevent the promotion of iron-based oxides. Fe2O3 nanoparticles with electronically conductive coating layers appear to be more efficient for improving......

sample is not any more corrosion-resistant, because more grain boundaries have come into being than in the amorphous state. Therefore, in this case, the nitridation will become much easier for iron-based... properties by slight nitridation was discussed on the basis of domain wall bulging model. Therefore for the Fe-based nanocrystalline soft magnetic alloy ribbons, the nitridation treatment can be used......

This is because an iron-based solid... properties of the Fe3Al based alloys were studied by spark plasma sintering from elemental powders (Fe-30Al, volume fraction, %) and mechanically alloying powders. The mechanically alloying powders were......
