Abstract

The effect of P addition on the thermal stability and on the glass forming ability (GFA) of bulk amorphous sheets and melt-spun ribbons of cast iron Ci00-xPx (x=1.56, 3.1, 4.63, 6.14, 7.63, 9.1 at.%) was studied by calorimetric measurements. Bulk amorphous sheets of 1 mm×4 mm transverse cross-section were prepared by centrifugal copper mold casting. For the as-quenched ribbons, it was found that only for x=7.63 and 9.1 glass transition temperatures Tg were detected. The reduced glass transition temperatures Tg/Tl (where Tl is the liquidus temperature) are 0.542 and 0.551, respectively. The as-quenched melt-spun ribbons and the bulk amorphous sheets have nearly the same thermal transition and glass forming ability characteristics.
