摘要：
In this work, effects of replacing Nb with either Mo or Zr on glass forming ability (GFA), thermal stability, magnetic and mechanical properties of [(Fe0.5Co0.5)(0.75)B0.2Si0.05](96)Nb-4 bulk metallic glass were studied. The rod and ribbon samples were prepared using copper mold casting and melt spinner respectively. The replacement of Mo instead of Nb does not affect the crystallization behavior but the GFA is decreased. However an increases in plasticity up to 4% and saturation magnetization (M-s) by 10% is observed for the equal atomic percentage of Mo, with further increase in the Mo content GFA still decreases (d(c) = 1 mm) and M-s remains the same. In case of [(Fe0.5Co0.5)(0.75)B0.2Si0.05](96) Zr-4 three distinct crystallization events were observed, the glass transition (T-g) and on set of crystallization (T-x) were decreased by 18 K and 23 K respectively. The GFA decreased drastically however the M-s remains the same. (C) 2016 Elsevier B.V. All rights reserved.
