Abstract

The effect of P addition on the thermal stability and on the bulk glass forming ability (BGFA) of cast iron based CiPxB4.35 (x = 4.35, 8.65, 10 at%) amorphous alloys was investigated by calorimetric (DSC and DTA) measurements. The amorphous alloys were prepared by melt spinning and by centrifugal copper mold casting. The crystallization kinetics was studied by DSC in the mode of continuos times linear heating and it was found that, both the glass transition temperature, Tg and the crystallization peak temperature, Tp are shifted to higher temperatures with increasing heating rate. The partial replacement of Ci by P atoms increases the thermal stability of the amorphous state and the BGFA. Bulk amorphous rods with diameters of 1, 1.5, 2, 2.5, and 3 mm as well as sheets with 1 × 4 mm 2 cross-section were prepared by centrifugal copper mold casting and the amorphicity of the melt-spun ribbons and of the mold cast rods was investigated by XRD, and HRTEM.
