Ferromagnetic Fe-based bulk metallic glasses with high thermoplastic formability

Viscosity and fragility of the supercooled liquids and melts from the Fe–Co–B–Si–Nb and Fe–Mo–P–C–B–Si glass-forming alloy systems

“…All values (see Table 1) are very close to those measured for other known BMGs [19,35] and are in good agreement with the maximum achievable diameter for which the samples are still amorphous: 3 mm for alloy A [36], 2 mm for alloy B (present work), 5 mm for alloy C [37] and 2.5 mm for alloy D [18]. Compared to other alloys, alloy C encounters a relatively lesser drop in viscosity magnitude in supercooled liquid region, which indicates the existence of a stronger relationship between better GFA and dynamic behavior of supercooled liquids.…”

Mechanical properties and structural features of novel Fe-based bulk metallic glasses with unprecedented plasticity

“…1 (b). Previously, such unprecedented high plasticity and flexibility can be obtained only in supercooled liquid state of Fe-based BMGs at high temperatures32. The reproducibility of the mechanical properties in the present work is quite good, indicating that the Fe 50 Ni 30 P 13 C 7 BMG with unprecedented plasticity is available as novel engineering materials.…”

Crystallization behavior of Fe- and Co-based bulk metallic glasses and their glass-forming ability

“…Some of Fe and Co-based BMGs are ferromagnetic [21,22] while (Fe,Ni,Co)eMoePeCeB BMGs exhibited good thermoplastic formability [23]. The influence of crystallization on the elastic and mechanical properties of Fe 36 Co 36 B 19.2 Si 4.8 Nb 4 bulk metallic glass was investigated recently [24].…”
