“…It represents its ability to resist the intrusion of hard objects locally. Sharifikolouei et al [17] explored how hardness could be improved in Ti-stabilized austenitic stainless steel, and their findings on a nano-indentation study of those fibres revealed an even larger improvement in hardness, reaching an average value of 14.2 1.0 GPa. The surface hardness of micro-formed specimens measures the service life of the workpiece, wear resistance, corrosion resistance and resistance to elastoplastic deformation.…”

Based on the experimental study of cavitation water jet impact on micro-forming, a single round hole micro-die was used in this paper. The effect of different process parameters on the performance of AISI 304 stainless steel foil was examined, which involves the nanometer hardness, and elastic modulus. The nano-indentation tester was used to test the nano-hardness of the formed part, and the performance of the workpiece before and after the impact was analyzed. The nano-hardness and elastic modulus increased significantly with an increase in the incident pressure. When the incident pressure was 20 MPa and the impact time of 5 min, the hardness increased by at least 122%, and the elastic modulus increased by at least 76%. After the cavitation water jet shocked the metallic foil of the SEM analysis and the results indicated that, as the incident pressure increases, the surface morphology of the formed part changes from approximately spherical to spherical, and the spherical roundness increases. In addition, there were different degrees of defects at the bottom of the formed part, and as the incident pressure increased, the bottom defects became more and more obvious, from micro-cracks to micro-layer cracks.

“…As a result, this technique can be applied to all metallic glass systems, making it a versatile approach for fabricating metallic glass microfibers. [14,15] Fe-based metallic glass systems, as soft magnetic materials, have great potential in applications in electronic information and green energy vehicles due to their low cost and excellent performance. Fe-rich metallic glasses offer increased saturation magnetic flux density (BS), leading to their utilization for electric appliances and devices.…”

Fe40Ni40B20 metallic glass is a key material among the many amorphous systems investigated thus far, owing to its high strength and appealing soft magnetic properties that make it suitable for use as transformer cores. In this study, Fe40Ni40B20 microfibers are fabricated down to 5 µm diameter. Three different melt–spinning wheel velocities: ≈51 m s−1, ≈59 m s−1, and ≈63 m s−1 (MG1, MG2, MG3) are used. Their fully amorphous structure is confirmed using X–ray diffraction, and differential scanning calorimetry (DSC) traces reveal a larger relaxation profile for the higher–quenched microfiber. Vibrating sample magnetometer measurements showed a higher saturation magnetization of 136 emug−1 for annealed metallic glass microfibers with a wheel velocity of 59.66 ms−1. Cylindrical magnetic field shields are obtained by aligning and wrapping the fibers around a cast. The observed anisotropic static field shielding behavior is in accordance with the microfibers' anisotropic nature. Composite samples are also produced by embedding the microfibers in an epoxy matrix to investigate their electromagnetic properties at GHz frequencies. Inclusion of the microfibers increase the composite's attenuation constant by 20 to 25 times, making it an ideal candidate for applications in the communications frequency range.
