Fe65Co10Ga5P12C4B4 glassy alloy powders were produced by high pressure Ar gas atomization of Fe65Co10Ga5P12C4B4 alloy ingot prepared by induction melting. The glass transition temperature (Tg), supercooled liquid region (ΔTx(=Tx-Tg)) of the glassy alloy powders are 730K and 50K. The glassy alloy powders have ferromagnetism with a Curie temperature (Tc) of 640 K and exhibits saturation magnetization (Is) of 1.18 T. No appreciable difference in the thermal stability and magnetic properties is seen between the glassy alloy powders and the melt-spun ribbon. By spark-plasma-sintering (SPS) these glassy alloy powders under the pressure of 80 MPa and at the temperature of 723 K below Tg, a bulk glassy Fe65Co10Ga5P12C4B4 alloy with a size of 20 mm in diameter and 5 mm in thickness was synthesized. Its relative density was about 96%. There was also no appreciable difference in the thermal stability between the bulk glassy alloy and the glassy alloy powders. This bulk glassy alloy exhibited saturation magnetization (Is) of 1.19 T and coercivity (Hc) of 115 A/m.
