Abstract

A new class of bulk metallic glasses (BMGs) the dual amorphous phased bulk metallic glass was studied with interest by researchers of materials science in the recent years, in order to bring together all the favorable properties for each amorphous phase. A dual phase bulk metallic glasses (DAPBMGs) fabricated by hot pressing using two different types of glassy alloy powder with the diameter of 10 mm and 5 mm in height were successfully achieved. The samples obtained were structural investigated by X-Ray diffraction (XRD), differential scanning calorimetry (DSC) and by scanning electron microscopy (SEM)..
