Bulk metallic glass composites with dual amorphous phases and soft magnetic properties were produced successfully by using hot-pressed technique. Zr-based amorphous powder was mixed homogeneously with Fe-based amorphous powder, and then hot-pressed in their liquid supercooled region. The compacts still display dual amorphous phase structure, and continuous viscosity connection among different amorphous phases. The magnetization curve shows that the structures still exhibit soft magnetic properties originating from the addition of the soft magnetic phase. The successful processing of new bulk metallic glasses (BMGs) with dual amorphous phases gives us a new design concept for new materials, especially for new glass function materials making use of unique softening characteristics of BMG alloys in their liquid supercooled regions.
