Abstract
Formation of metallic glass largely depends on the composition of the alloy system and inherent glass forming ability (GFA). Among all the relevant GFA criteria, GFA parameter, PHSS, gives better quantitative description to explain higher GFA in multicomponent systems. Present work shows a set of glass forming alloys designed with the help of some GFA parameters including PHSS using a raw blast furnace (BF) grade metal, popularly known as pig iron, in the range of 75–100 wt% of the total alloy weight and addition combination of alloying elements (B, P, Nb, Cr, Mo). Good glass forming ability of the blast furnace hot metal (direct from blast furnace containing impurities) as determined by thermodynamic calculation has been experimentally validated by making its glassy ribbons by melt spinning in air as well 1 mm diameter partially glassy rod as confirmed by X-ray diffraction (XRD), transmission electron microscopy (TEM) and differential scanning calorimetry (DSC) studies.
