“…Generally, such alloys exhibit relatively appropriate soft magnetic behavior with excellent microhardness. [90,91] As reported by Wang et al [92] addition of different amounts of Nb (up to 6%) into Fe-Cr-Mo-Co-C-B-Nb improves the surface properties, coatingsubstrate interface, and AFA significantly. However, the presence of excessively high Nb elements produces Nb-Mo phase, which reduces the flexibility of the coating.…”

Fe‐based amorphous alloy coatings (Fe‐AACs) have exhibited appropriate corrosion and wear resistance and improve the performance of material surfaces. This study summarizes the advances related to Fe‐based amorphous alloys pertaining to their chemical compositions and manufacturing processes and their associated effect on the amorphous structure, microstructure and properties. In particular, Fe‐based amorphous alloy coatings produced by laser cladding are investigated in order to study the effect of amorphous structure, partial crystallization, and composition on the microstructure, hardness, corrosion and wear resistance of these coatings. In addition, the effect of laser parameters (power and scanning speed) on the geometric and metallurgical characteristics of produced amorphous coatings are also covered.This article is protected by copyright.

“…They pointed out that the system exhibits good soft-magnetic properties: H c = 2.5–7.0 A m −1 , μ i = 4910–15,830, and B s = 0.40–0.48 T [ 22 ]. An interesting study of preparing bulk nano Fe-Si-B-Cu-Nb based alloys by mechanical alloying has been recently reported [ 23 ]. This alloy was consolidated into bulk nanocrystalline objects, using spark plasma sintering (SPS) technique.…”

Metallic glasses, with their short-range order structure, exhibit unique characteristics that do not exist in the corresponding crystalline alloys with the same compositions. These unusual properties are attributed to the absence of translational periodicity, grain boundaries, and compositional homogeneity. Cobalt (Co)-based metallic glassy alloys have been receiving great attention due to their superior mechanical and magnetic properties. Unluckily, Co-Ti alloys and its based alloys are difficult to be prepared in glassy form, due to their rather poor glass-forming ability. In the present work, the mechanical alloying approach was employed to investigate the possibility of preparing homogeneous (Co75Ti25)100−xBx starting from elemental powders. The feedstock materials with the desired compositions were high-energy ball-milled under argon atmosphere for 50 h. The end products of the powders obtained after milling revealed a short-range order structure with a broad amorphization range (2 at% ≤ B ≤ 25 at%). The behaviors of these glassy systems, characterized by the supercooled liquid region, and reduced glass transition temperature, were improved upon increasing B molar fraction. The results had shown that when B content increased, the saturation magnetization was increased, where coercivity was decreased.

“…This indicates that the material may exhibit reduced mechanical properties at elevated sintering temperatures even when high density and low porosity are attained due to rapid grain growth. The advantages of SPS, such as lower sintering temperature and shorter consolidation, have aided the development of nanostructured materials compared to conventional processing routes [ [76] , [77] , [78] ].…”
