Publication number: 20220372604Abstract: Embodiments disclosed herein relate to the production of amorphous metals having compositions of iron, chromium, molybdenum, carbon and boron for usage in additive manufacturing, such as in layer-by-layer deposition to produce multi-functional parts. Such parts demonstrate ultra-high strength without sacrificing toughness and also maintain the amorphous structure of the materials during and after manufacturing processes. Two additive manufacturing techniques are provided: (1) the complete melting of amorphous powder and re-solidifying to amorphous structure to eliminate the formation of crystalline structure therein by controlling a heating source power and cooling rate without affecting previous deposited layers; and (2) partial melting of the outer surface of the amorphous powder, and solidifying powder particles with each-other without undergoing a complete melting stage. Amorphous alloy compositions have oxygen impurities in low concentration levels to optimize glass forming ability (GFA).Type: ApplicationFiled: August 5, 2022Publication date: November 24, 2022Inventors: John KANG, Ricardo Salas, Evelina Vogli
