Optimum alloy compositions of the Ni-Nb-Cr-Mo-P-B, Ni-Cr-Nb-P-B and Ni-Cr-Mo-P-B glassy alloys were investigated for trail production of separator of fuel cell. Eventually the Ni60Nb2Cr16Mo2P16B4, Ni65Cr10Nb5P16B4 and Ni65Cr10Mo5P16B4 glassy alloys were chosen from the viewpoint of having a wide supercooled liquid region.<BR>Then the groove formability of the compositionally optimized alloys in a supercooled liquid state was studied by hot-pressing with the dies having precise grooves. A precise groove forming can be achieved by hot-pressing the Ni60Nb2Cr16Mo2P16B4 and Ni65Cr10Mo5P16B4 glassy alloys in a supercooled liquid state at Tg + 20 K. However, it was difficult to form the precise grooves in the Ni65Cr10Nb5P16B4 glassy alloy.<BR>Finally, we successfully demonstrated that it is possible to form the grooves by hot-pressing using viscous flow deformation in a supercooled liquid state and to produce metallic glassy separators for proton exchange membrane fuel cells (PEMFC).
