The consolidations of two bulk amorphous Fe 40 Ni 40 P 14 B 6 alloy discs are performed via hot pressing for a short time in its supercooled liquid region under a pressure of ∼1.2GPa. When the consolidated temperature T s is lower, the conjunction of two bulk amorphous Fe 40 Ni 40 P 14 B 6 alloy discs cannot be achieved. Only when T s get to the vicinity of 675K, two amorphous Fe 40 Ni 40 P 14 B 6 alloy discs have low viscosity enough to be fully fused together in a short time and the resulting compacts retain ∼90% amorphous phase. To further improve the consolidated temperature T s , a vast amount of crystallization will occur and result in the embrittlement of amorphous alloy.
