To consolidate [(Fe0.5Co0.5)0.75Si0.05B0.2] 96 Nb4 metallic glassy powder to full density, a pressurized liquid phase sintering was employed, which was intended to promote a viscous flow deformation of solid particles and also to enhance the intergranular permeation of the liquid phase. Al-32.5wt.%Cu was chosen as a liquid phase component having low melting point. The mixed powders were sintered by induction heating furnace with heating rate of 200 K/min and applying pressure of 400 MPa for maintaining the amorphous phase. SEM and TEM observations shows the interfacial reaction layers were formed between metallic glassy phase and liquid phase. While this layer can contribute for to reinforce the fracture strength, the layer interferes with deformation of metallic glassy powders and also interferes with squeezing of liquid phase. This study report the interfacial microstructure between the powder particles by TEM observations.
