Modification of Glassy Alloy Used for Bipolar Plates of Fuel Cells in High Magnetic Field

摘要

The glassy alloy Ni_(53)Nb_(20)Ti_(10)Zr_8Co_6Cu_3 is modified with heat treatment and high magnetic field treatment, and characterized by means of XRD, DSC, microhardness analysis, as well as resistivity measurement. The results indicated that crystalloid phase was formed after heat treating under the condition of 860K for 10 minutes, which caused hardness to increase and resistivity decrease. And then treated under the condition of 673K and 10T high magnetic field for 3 hours, the grains were refined and resistivity was decreased furthermore.
