Magnetic and corrosion properties of Fe56Co7M2Mo5Zr10B20 (M=W or Ni) bulk metallic glasses

The effect of Hf substitution for Zr on glass forming ability and magnetic property of FeCoZrMoBAlY bulk metallic glasses

“…However, almost all of the above-mentioned Fe-based BMGs were prepared using high purity raw materials, because even a trace amount of oxygen and other impurities would induce the heterogeneous nucleation and reduce drastically the glass forming ability (GFA). In order to broaden their application in industries, tremendous efforts have been made to enhance the GFA and properties of the magnetic Fe-based BMGs by composition and structure design on one hand [7,8], and decrease the cost by using industrial raw materials and conventional elements on the other hand [9,10].…”

Casting vacuum effects on the precipitates and magnetic properties of Fe-based glassy alloys

“…For example, the formation of NiZr 2 in the amorphous matrix can be triggered by oxygen [1]. Moreover, the crystalline ZrB 2 appears dominantly in the amorphous Fe-Co-Zr-M-Mo-B cylinder with diameter of 2.5 mm [30] and ZrB 12 was formed as a priority in the bulk Fe 61 B 15 Zr 5 Mo 7 Co 5 Y 2 Cr 2 glass after annealing at 650°C under 10 3 Pa oxygen pressure [31]. Hence, it is understood that the percentage of Zr-B compounds in the samples with c W =0 and 2 at.% prepared under VL condition is higher compared to other samples (Table 4).…”

Structure and thermal behavior of multicomponent Fe68−xNixZr15Nb5B12 (x=5, 10, 15, 20) alloys

“…The effect of multicomponent is probably due to the "confusion principle": the more elements involved, the lower the chance that the alloy can select viable crystal structures, and the greater the chance of glass formation [12]. The large supercooled liquid regions of Fe-based alloys are observed in Fe 56 Co 7 W 2 Mo 5 Zr 10 B 20 alloy (92 K) prepared by copper mould casting [13] and (Fe 50 Co 50 ) 62 Nb 8 B 30 alloy (102 K) prepared by melt spinning [14]. In this work, multicomponent Fe 68−x Ni x Zr 15 Nb 5 B 12 * Tel.…”
