The results demonstrate that the HE-BMGs exhibit outstanding supercooled liquid stability and high GFA. Notably, a Co35Fe35Nb5B20P5 HE-BMG possesses a large supercooled liquid region (ΔTx) of 66 K and a critical diameter for glass formation (dc) of 2.0 mm. Compared to a Co70Nb5B25 counterpart, the Co35Fe35Nb5B20P5 HE-BMG exhibits distinct sluggish crystallization behavior and higher crystallization activation energy, despite both alloys precipitating a similar complex Fe23B6-type phase during initial crystallization. The HE-BMGs also exhibit excellent soft magnetic and mechanical properties with saturation magnetic flux density, coercivity, effective permeability at 100 kHz, yielding strength, and compressive plastic strain of 0.93–1.02 T, 2.9–6.7 A/m, 7000–7700, 4091–4163 MPa, and 0.3–1.0 %, respectively.

To unravel the role of Nb in tailoring alloy properties, correlations between doping content and key characteristics including thermal hysteresis, compressive plasticity, and electrochemistry behavior were established. The XRD analyses showed that all the alloys showed typical amorphous structure without crystallization or phase separation. Thermodynamic analyses show that the addition of Nb can enhance the thermal stability of the alloy, but when its content exceeds 3 at.%, the glass forming ability (GFA) decreases. Mechanical tests show that the alloy has the best overall performance at x = 3 at.%, with the yield strength and plasticity reaching 1673.0 MPa and 6.9%, respectively, which are 101.2 MPa and 4.6% higher than that of the base alloy (x = 0); microscopic characterization reveals that an appropriate amount of Nb promotes the branching and expansion of shear bands through the atomic size effect, thus enhancing the plasticity. Electrochemical tests showed that the alloy at x = 3 at.% had the lowest self-corrosion current density (2.24 × 10-8 A/cm²) and the highest charge transfer resistance (Rct) in 3.5% NaCl solution.

The study aimed to elucidate the conduction mechanisms and evaluate the potential applications of these materials. AC conductivity investigation using the Almond-West formalism yielded important characteristics including crossover frequency (ωH), DC conductivity (σdc), and frequency exponent (s). The results showed that conduction occurs via a non-overlapping small polaron tunneling process. Furthermore, the imaginary electric modulus, as studied by the Kohlrausch-Williams-Watts function, showed non-Debye relaxation behavior, with compositional effects becoming more significant at higher frequencies.Temperature-dependent impedance investigation and modeling with an analogous circuit indicated that ionic and polaronic conduction, as well as Li+ ion diffusion, occurs simultaneously in LVB4, LVB5, and LVB6 glasses. The activation energy estimated from conductivity, electric modulus, and impedance analyses revealed a significant connection, confirming the consistency of the results.
