Formation, thermal stability and mechanical properties of high entropy (Fe,Co,Ni,Cr,Mo)-B amorphous alloys

Change of electronic properties on transition from high-entropy to Ni-rich (TiZrNbCu)1−xNi alloys

“…This may be influenced by the fact that glass forming ability (GFA) of known a-HEAs is inferior in comparison to the best glass former in a particular alloy system [15,17,33]. However, in the last couple of years several comprehensive studies showing novel effects in a-HEAs have been published (e.g., [33,34,35,36,37,38]).…”

Structure property relationship in (TiZrNbCu)1−xNix metallic glasses

“…Further, the critical thickness of HE-BMGs is generally lower than that of conventional BMGs [15]. More recently the situation has started to change and several studies showing the conceptual and technological relevance of a-HEAs appeared [18,34,35,36].…”

Glass Forming Ability, Thermal Stability, and Magnetic Properties of FeCoNiBSi Alloys with Different B Contents

“…e amorphous structures with the broad peaks at around 2θ � 45°can be found at the annealing temperatures of 678 K and 698 K. However, as the annealing temperature is up to 718 K, a diffraction peak at 2θ � 44°corresponding to c- [Fe,Ni] is observed in the XRD patterns. Moreover, two obvious diffraction peaks at 2θ � 44°a nd 46°corresponding to c- [Fe,Ni] and Ni 2 B [21], respectively, can be detected within the annealing temperature of 738 K. Figure 3, the decrease of the Hc can be attributed to the relief of internal residual stress and the reduction of magnetocrystalline anisotropy [12,17]. When the ribbons are annealed at higher temperature, the Hc increases rapidly because of the excessive growth of precipitations of c- [Fe,Ni] …”

“…It is well known that Fe-B amorphous alloys can be formed in the composition with B content in the range of 12-28% at.% [16] by melt-spinning process. Wang et al [17] indicated that amorphous phases can be formed in a wide B-content range of 11∼31 at.% for (Fe,Co,Ni,Cr,Mo)-B amorphous alloys. Moreover, Yao et al [18] investigated the effect of B content on crystallization, forming ability, and magnetic properties of FeZrBNb amorphous alloy and showed that only one exothermic peak can be observed in the DSC curves when B content exceeds 20 at.%.…”
