Composition dependent characteristic transition temperatures of Co-B melts
Source abstract
Abstract
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 (θp(LI), θp(LII)) 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, θp(LI) and θp(LII) 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.
