Abstract Scope |
In this study, the crystalline zirconium-based (Zr-based) alloys foil was used to fabricate bulk metallic glass using the laser-foil-printing (LFP) process. Through laser spot pattern welding, the crystalline phase of NiZr2 and its oxides in Zr-based crystalline foil were remelted and disordered to form bulk metallic glass (BMG) parts. BMG parts fabricated from amorphous foil and crystalline foil were characterized and compared for the amorphous structure through X-Ray diffraction (XRD). The microhardness revealed similar mechanical properties of LFP-fabricated BMGs using different crystalline types of feedstocks. Moreover, in the transmission electron microscope (TEM) results of BMGs, the select area electron diffraction (SAED) pattern and the bright-field (BF) images show a typical amorphous structure, indicating the feasibility of using the crystalline foil. |
