Fe based bulk metallic glass alloys although known for wear and corrosion resistance, are extremely brittle in nature. The effect of addition of Ni powder to Fe based amorphous powder is investigated in the present study. Ductile Ni in Fe BMG matrix, is known to prevent crack propagation through shear localisation, when loaded in compression. Also, as Ni crystallises at a lower temperature than Fe amorphous powder, it can toughen the resultant composite, thus improving its wear characteristics. Ni and Fe based amorphous powders of composition Fe48Cr15Mo14Y2C15B6 (at. %) have been ball milled for 2 hours. At volume fractions varying from 2.5%- 15% of Ni, these powders were spark plasma sintered at 550˚ C and 50 Mpa pressure. Microstructure was observed through SEM and phase evaluation has been done using XRD. The results of wear and compression testing will be discussed.
