Amorphous Co_<75>Si_<10>B_<15> alloy powders which show a remarkable softening between T_g and T_x and a wide temperature range, ΔT(T_x-Tg=59 K), were subjected to consolidation in a vacuum with a hot press apparatus. Amorphous alloy bulk which has 5 mm in diameter, 1.7 mm in height and 96% in compaction degree was obtained at the optimum temperature and pressure. This alloy bulk exhibited a compression strength as high as 1.38 GPa. It was confirmed that a higher pressure was merely effective to densificate the compact but that a proper temperature for softening of powders as well as pressure was required to perform denser and stronger consolidation. Magnetic properties of the amorphous alloy bulk obtained were compared with those of the dynamic alloy compacted bulk. Soft magnetic properties of the hot-pressed compact was superior to those of the dynamical compact before heat-treatments. However, those properties of dynamical compact was improved by annealing, while those of the hot-pressed one were entirely insensitive to annealing treatments.
