Abstract

Amorphous metal alloys have been developed with sufficiently slow crystallization kinetics to allow the casting of bulk metallic glass (BMG) components up to several centimeters in cross section. Mechanical characterization of these castings has shown that these new BMG alloys have high modulus, high elastic limits and high hardness, as compared to crystalline metal alloys. The extension of this technology to the production of large structural amorphous metal components will require the consolidation of amorphous particles. NIST, MATSYS, and ARL are studying the response of several amorphous metal alloys to HIP consolidation. This paper will present the results of these studies on consolidated monolithic BMG alloys and tungsten-BMG composites. Recent results on the HIP consolidation mechanics and the resultant microstructures of the samples are discussed.
