One of the current limitations in producing bulk metallic glass components of sufficient scale for structural application is the low critical casting thickness available with current amorphous alloy systems. Currently, iron-based glass forming alloys (Fe48Cr15Mo14Y2C15B6) can be cast into fully amorphous ingots approximately 12mm in diameter. With laser additive manufacturing, material and heat are added incrementally, theoretically leading to the fabrication of much larger amorphous structures than currently achievable with casting alone. The paper will focus on thermal modeling and experimental processing of laser deposited Fe-based bulk amorphous metallic components.
