Abstract: Zr-Cu-Al metallic glasses were formulated with differing compositions to determine their thermophysical properties. It was determined that by decreasing the zirconium content of the metallic glass, the thermal conductivity can be increased. The maximum value of thermal conductivity was found for the metallic glass with a composition of Zr:Cu:Al = 50:39.3:10.7 (at. %). It was found that although the metallic glasses did not crystallize with heat treatment below Tg, they did begin to crystallize with heat treatment above the glass transition temperature. The thermal conductivity of the glasses increased with the progress of crystallization.
