Abstract

The temperature-dependent liquid structures of Co-B melts were studied by in-situ measuring the magnetization. A magnetization anomaly in term of the non-Curie-Weiss temperature dependence of magnetization was observed in the overheated state, demonstrating a temperature-induced liquid-liquid structure transition. This anomalous behavior was found to be a universal formula for the Co-B binary alloy system. The transition point (T₀) and two paramagnetic Curie temperatures (θ_p(L_I), θ_p(L_II)) corresponding to two distinct kinds of liquids (i.e., high-magnetization liquid (HML) I and low-magnetization liquid (LML) II) were measured. With the increased concentration of Co, T₀, θ_p(L_I) and θ_p(L_II) shift to higher temperatures and the Curie constants for the HML and LML decrease. Based on the location of T₀, a guideline is drawn above the liquidus in the Co-B phase diagram, which could provide a significant guidance to the practical melt treatment.
