发明名称 Amorphous Steel Composites with Enhanced Strengths, Elastic Properties and Ductilities
摘要 Amorphous steel composites with enhanced mechanical properties and related methods for toughening amorphous steel alloys. The composites are formed from monolithic amorphous steel and hard ceramic particulates, which must be embedded in the glass matrix through melting at a temperature above the melting point for the steel but below the melting point for the ceramic. The ceramics may be carbides, nitrides, borides, iron-refractory carbides, or iron-refractory borides. An optical micrograph of such a composite including niobium carbide particulates is shown in FIG. 2A. The produced composites may be one of two types, primarily distinguished by the methods for embedding the ceramic particulates in the steel. These methods may be applied to a variety of amorphous steels as well as other non-ferrous amorphous metals, and the resulting composites can be used in various applications and utilizations.
