Abstract: 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). Specific techniques of additive manufacturing include those based on lasers, electron beams and ultrasonic sources.

Abstract: A method for producing long metal products includes the steps of receiving long intermediate products traveling on respective continuous casting lines, to an exit area, and subsequently introducing products from the exit area into a production plant having known layout parameters; the production plant has a rolling mill for rolling the products; interconnected production lines between the exit area of the casting machine and the rolling mill, the production lines define production paths or routes; and a first and a second heating devices. The method associates a mathematical model to the production plant for dynamically calculating a reference value, or Global Heating Cost Index, correlated to heating devices; automatically determining for the intermediate products the production path or route that minimizes the reference value, or Global Heating Cost Index; and eventually automatically routing each of the products along the determined production path which minimizes the reference value, or Global Heating Cost Index.
