Abstract : A series of Pd-Si based alloy glasses were formed by quenching melts to room temperature at various cooling rates. Certain ternary alloys of Pd-Au-Si, Pd-Ag-Si and Pd-Cu-Si formed glasses with thicknesses greater and 1 mm at cooling rates as low as 100C/sec. The glass-liquid transition was exhibited thermally by both binary and ternary alloys. The rheological manifestations of the glass transition was observed qualitatively for certain of the ternary alloys. The electrical resistivity of the alloys in their various states were also measured.
