“…Similar to titanium, the grain size of Al can be reduced to a sub-micron scale with the increasing pass. Aal et al showed that the average grain size of pure Al was 1.7 µm after two passes of ECAP and decreased to 0.43 µm and 0.23 µm after four and ten passes at room temperature through route A, respectively [58]. The same conditions are applied in his other articles paper, it was also found that the average grain size was reduced from 390 µm to 1.8 µm, 0.4 µm and 0.3 µm after two, four and ten passes, respectively [59].…”

“…After research, Fe-based MG has also been clearly shown to successfully remove organic matter from wastewater [57]. Fe-based amorphous alloys are known for its high corrosion resistance, and Fe-based amorphous alloys not only exhibited high corrosion resistance in conventional environments, Pratap et al [58] further demonstrated that Fe-based amorphous alloys can still have excellent corrosion resistance under simulated body fluids. Although the surface of the Fe-based amorphous alloy is corroded in the simulated body fluids, the surface morphology does not change much (Figure 7).…”

“…Also limiting the industrial applications of amorphous alloys are their record-breaking strength and hard- Obviously, amorphous alloys have many excellent properties. Amorphous alloys have some record-breaking excellent physical and chemical properties, such as strength, toughness, hardness, and modulus, which break the record for metallic materials [54,[56][57][58][59][60][61][62], almost every type of amorphous alloy reaches several times the strength of the crystalline material of the same alloy family. Some amorphous alloys also have excellent soft magnetic properties, catalytic properties, and good wear resistance and are widely used in various applications [63,64].…”

Amorphous alloy is an emerging metal material, and its unique atomic arrangement brings it the excellent properties of high strength and high hardness, and, therefore, have attracted extensive attention in the fields of electronic information and cutting-edge products. Their applications involve machining and forming, make the machining performance of amorphous alloys being a research hotspot. However, the present research on amorphous alloys and their machining performance is widely focused, especially for Fe-based amorphous alloys, and there lacks a systematic review. Therefore, in the present research, based on the properties of amorphous alloys and Fe-based amorphous alloys, the fundamental reason and improvement method of the difficult-to-machine properties of Fe-based amorphous alloys are reviewed and analyzed. Firstly, the properties of amorphous alloys are summarized, and it is found that crystallization and high temperature in machining are the main reasons for difficult-to-machine properties. Then, the unique properties, preparation and application of Fe-based amorphous alloys are reviewed. The review found that the machining of Fe-based amorphous alloys is also deteriorated by extremely high hardness and chemical tool wear. Tool-assisted machining, low-temperature lubrication assisted machining, and magnetic field-assisted machining can effectively improve the machining performance of Fe-based amorphous alloys. The combination of assisted machining methods is the development trend in machining Fe-based amorphous alloys, and even amorphous alloys in the future. The present research provides a systematic summary for the machining of Fe-based amorphous alloys, which would serve as a reference for relevant research.

“…Among iron systems, amorphous Fe-based alloys are counted to be one of the best-performing materials because of their superior corrosion and wear resistance and relatively low cost compared to their crystalline counterparts [45][46][47][48][49][50][51][52][53] . The biocorrosion of amorphous Fe-based alloys was studied in different biological solutions, including arti cial saliva and phosphate-buffered saline, where the passive behavior in these media makes them ideal candidates for orthopedic and dental applications 54 . There is a considerable number of reports in the literature on the synthesis and characterization of amorphous micro/nano bers [55][56][57][58][59] .…”

The resistance of commercial stainless steel (SS) types in harsh environments is problematic because of the breakdown of the passive chromium oxide layer. This study reports fully amorphized 316 SS microfibers using a customized multi-nozzled melt-spinning technique. Electrochemical tests in 3.5 wt.% NaCl shows a high corrosion resistance with an annual corrosion rate of less than 60 µm year–1 under ambient conditions, which increases slightly as the temperature rises to 50°C. The room temperature sample also shows a low passivation current at the level of 10–4 A cm–2 with long-term stability, and no pitting is observed for all the samples until 1.5 V. The sample polarized at 37°C shows the smallest bulk resistance (~ 1400 Ω cm2) and the largest double-layer capacitance (28.6 µF cm–2), where large amounts of salt accumulation on the surface creating a passive layer on the microfibers were detected by energy dispersive X-ray (EDX)–scanning electron microscopy. Cross-sectional investigation by EDX-scanning transmission electron microscopy corroborates the homogenous bulk composition and Fe-rich, Ni and Cr-containing amorphous oxides, both of which contribute to the enhanced corrosion and passivation properties compared to commercial SS counterparts in the literature.
