    摘要： 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.

    摘要： The present invention provides a high thermal conductivity iron-copper (Fe—Cu) alloy and a method of manufacturing the same. The present invention provides an iron-copper alloy containing 55 to 95 atomic % of iron and 5 to 45 atomic % of copper. The present invention also provides an iron-copper alloy manufacturing method including a first step of preparing a melting furnace; a second step of adding iron and copper to the melting furnace and performing dissolution and molten metal formation so as to contain 55 to 95 atomic % of iron and 5 to 45 atomic % of copper based on the weight of the iron-copper alloy; a third step of stabilizing the molten metal; and a fourth step of pouring the stabilized molten metal into a casting mold and performing casting. The present invention provides an iron-copper alloy that is an iron-based alloy containing iron as a main component and having high thermal conductivity and mechanical properties along with, for example, an electromagnetic-wave shielding property and a soft magnetic property, which can be widely used for metal parts and electronic parts and machine parts.

    摘要： 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.
