1. Bulk metallic glass composites (BMGCs) are an effective strategy to enhance the ductility of bulk metallic glasses (BMGs).
2. Laser additive manufacturing (LAM) is used to fabricate a multi-layered Zr-based BMGC with a well-controlled gradient in volume fraction of the crystalline dendrites.
3. The gradient BMGC shows an exceptional combination of yield strength and tensile ductility, attributed to the synergetic strengthening from the interaction of the adjacent layers and the asynchronous deformation mode associated with the heterogeneous microstructure.
The article “Controllable additive manufacturing of gradient bulk metallic glass composite with high strength and tensile ductility” is a reliable source of information on the development of bulk metallic glass composites (BMGCs). The article provides a comprehensive overview of existing processing techniques for BMGCs, as well as their limitations, before introducing laser additive manufacturing (LAM) as an alternative method for fabricating multi-layered Zr-based BMGCs with a well-controlled gradient in volume fraction of the crystalline dendrites. The article then goes on to discuss how this new method has enabled an exceptional combination of yield strength and tensile ductility, attributed to synergetic strengthening from the interaction of adjacent layers and asynchronous deformation mode associated with heterogeneous microstructure.
