Abstract:
1. A method of forming molded articles having high elastic limits comprising: providing a feedstock of bulk-solidifying amorphous alloy having a glass transition (T heating the feedstock to a molding temperature molding the feedstock for a time less than a specified maximum permissible molding time at temperatures less than a specified maximum molding temperature around the glass transition temperature of the feedstock to form a molded article such that the molded article retains an elastic limit of at least 1.2%, wherein the maximum molding temperature is proportional to the size of the ΔTsc and wherein the specified permissible molding time is proportional to both the molding temperature and the ΔTsc; and wherein the ΔTsc of the feedstock is more than 90° C., and the maximum molding temperature is given by a value selected from the group consisting of (Tsc+½ ΔTsc), (Tsc+¼ ΔTsc), and Tsc.
