In recent years, the dual amorphous phased bulk metallic glass (DAPBMGs) was studied with interest by researchers of materials science, which is a new class of bulk metallic glasses (BMGs). These materials consist of several amorphous phases and are expecting to bring together all the favorable properties for each phase. The DAPBMGs with soft magnetic properties can be obtained by powder metallurgy process; the amorphous powders can be produced either by mechanical alloying (MA) or by high pressure Ar gas atomization. Compacting of the glassy alloy powder to obtain the dual amorphous phased bulk metallic glass can be achieved by using a hot-pressed technique (HP) or by spark plasma sintering (SPS) process, in the supercooled liquid region of the amorphous phases. There are presented some families of dual amorphous phased bulk metallic glass (DAPBMGs) with soft magnetic properties. This paper synthesizes the current work of the researchers that is the processing, characterization and understanding of these new classes of materials, the dual amorphous phased bulk metallic glass with soft magnetic properties.
