Compaction of bulk amorphous Fe40Ni40P14B6 alloys

[摘要] The consolidations of two bulk amorphous Fe40Ni40P14B6 alloy discs are performed via hot pressing for a short time in its supercooled liquid region under a pressure of similar to 1.2 GPa. When the consolidated temperature T, is lower; the conjunction of two bulk amorphous Fe40Ni40P14B6 alloy discs cannot be achieved. Only when T-s get to the vicinity of 675 K, two amorphous Fe40Ni40P14B6 alloy discs have low viscosity enough to be fully fused together in a short time and the resulting compacts retain similar to 90% amorphous phase. To further, improve the consolidated temperature T-s,T- a vast amount of crystallization will occur and result in the embrittlement of amorphous alloy. (C) 2007 Elsevier B.V. All rights reserved.
