“…In addition, Fe-W interface plays an important role in various properties of Fe-W products, e.g., hydrogen is more easily trapped by Fe/W interface, and the hydrogen solubility of Fe/W interface is higher than that of bulk W or Fe [13]. In this respect, a lot of researches in the literature are focused on absorption performance [13], magnetic properties [14], cascade collision [15], and fabrication [16], etc. Nevertheless, the stress-strain behaviors and dislocation evolution of the Fe-W interface have not been reported in the literature.…”

Molecular dynamic simulations based on a recently constructed potential reveal that quasi-repeating patterns could appear in both Fe(110)/W(110) and W(110)/Fe(110) interfaces, and that three kinds of atomic displacements of Fe atoms because of the Fe–W interaction intrinsically bring about the interesting quasi-repeating patterns of the Fe–W interfaces. It is also found that the Fe–W interface becomes more brittle with less critical strains under tensile loading than pure Fe or W, which is fundamentally attributed to the movement of the interface dislocations as a result of the lattice mismatch between Fe and W. Interestingly, the dislocation loops could be formed in the Fe–W interface under tensile loading due to the pinning of the 100 edge dislocations by the edge dislocations of 1 / 2 111 , whereas no dislocation loop would be generated in pure Fe or W.

“…During recent years, the growth of Fe films on the substrate of W, i.e., Fe/W interface, has attracted a lot of research interests among scientists, mainly due to its fascinating magnetic properties as a function of overlayer thickness [1][2][3][4][5][6][7][8][9][10][11][12]. Another well-studied property of various Fe/W interfaces is the work function, which seems very important for the performances of the Fe/W materials utilized as the promising source of spin-polarized electrons of field emission tips [13][14][15][16][17].…”
