Abstract
Systems and methods for developing tough hypoeutectic amorphous metal-based materials for additive manufacturing, and methods of additive manufacturing using such materials are provided. The methods use 3D printing of discrete thin layers during the assembly of bulk parts from metallic glass alloys with compositions selected to improve toughness at the expense of glass forming ability. The metallic glass alloy used in manufacturing of a bulk part is selected to have minimal glass forming ability for the per layer cooling rate afforded by the manufacturing process, and may be specially composed for high toughness.
