A new synthesis technique will be applied to production of intermetallic compounds and amorphous alloys with ultrafine grain sizes. The technique allows ease of compositional and impurity control and provides extremely high cooling rates so that amorphous alloys can be created. The research is testing new ideas about low-temperature sintering of the material such that crystallization and grain growth is limited during densification. Evolution of phases during transitions from the extremely metastable condition are being followed using single- and two-phase materials. Processing-structure and structure-property relationships will be developed using x-ray diffraction, Rutherford backscattering, scanning calorimetry, microscopy, density, and mechanical property measurements.
