Özet
In this study, effects of simultaneous Mo and W substitution for Nb additions on the stability and magnetic properties of Fe-Co-based bulk metallic glass (BMG) alloys fabricated by centrifugal casting are investigated. The saturation magnetization (Js) and coercivity (Hc) for the as-cast Fe36Co36B19.2Si4.8X 4 (X = Nb or Mo0.5W0.5) BMG alloys and melt-spun Fe36Co36B19.2Si4.8Mo 2W2 were in the range of 1.02-1.57 T and 11.13-1685 A/m, respectively. The Fe36Co36B19.2Si 4.8X4 (X = Nb or Mo0.5W0.5) BMG alloys in the shape of wedge with the maximum thickness of 1.5-2 mm were obtained successfully by means of conventional centrifugal casting. Replacing Nb with Mo0.5W0.5 deteriorates magnetic properties in bulk form and reduces the GFA of the alloy due to promoting the precipitation of non-magnetic compounds, while it results in good soft magnetic properties in melt-spun ribbon form. © 2010 Elsevier B.V.
