摘要： A system for generating a user-adjustable furnace profile, comprises a user interface configured to receive one or more materials properties from a user, a processor, and a memory with computer code instructions stored thereon. The memory is operatively coupled to the processor such that, when executed by the processor, the computer code instructions cause the system to implement communicating with a furnace to ascertain one or more thermal processes associated with the furnace, identifying one or more object characteristics associated with an object to be processed by furnace, and determining a thermal processing parameter profile of at least one thermal processing parameter corresponding to each of the thermal processes, based on (i) the one or more part characteristics and (ii) the one or more materials properties, the thermal processing parameter profile characterizing a cycle of the one or more thermal processes.

摘要： An apparatus for producing a three-dimensional multilayer object produces a three-dimensional multilayer object by partially applying energy to a conductive powder and thereby melting or sintering and curing the conductive powder. The apparatus for producing a three-dimensional multilayer object includes: a holding unit holding the conductive powder, and holding the cured three-dimensional multilayer object; an energy application unit applying energy to the conductive powder held by the holding unit; a probe disposed spaced apart from a surface layer portion of the cured three-dimensional multilayer object and detecting a flaw in the surface layer portion; and a probe moving mechanism relatively moving the probe with respect to the surface layer portion. The probe contains an excitation coil generating an eddy current in the surface layer portion, and a detection coil detecting a change in a magnetic field of the surface layer portion.

摘要： A compound sintering furnace with managed contamination for debinding and sintering parts. An inner insulation layer is disposed within an outer insulation layer and has an internal hot face surrounding a work zone. A sealed housing surrounds the inner insulation layer and is composed of a refractory material capable of withstanding a service temperature greater than a debinding temperature and less than a sintering temperature. An outer heater system is configured to heat at least a portion of the sealed housing and externally heat the inner insulation layer to, in conjunction with an inner heater system, heat the work zone to the debinding temperature, and inhibit condensation of a binder within and upon the inner insulation layer during a debinding process. The inner heater system is configured to internally heat the inner insulation and heat the work zone to the sintering temperature.

摘要： Methods for producing final bodies that contain a fine-grained refractory complex concentrated alloy (RCCA), as well as RCCAs, intermediate materials and final bodies containing the RCCAs, and high-temperature devices formed by such final bodies. Such a method includes providing a precursor with one or more precursor compounds containing elements of an RCCA, reducing the precursor compounds in the precursor via reaction with a reducing agent so as to generate the RCCA and a compound comprising a product of the reaction between the reducing agent and the precursor compounds, generating a solid material that contains at least the RCCA, forming with the solid material a porous intermediate body, and consolidating the porous intermediate body so as to partially or completely remove the pore volume from the porous intermediate body, and in doing so yield either a denser final body or a denser film.

摘要： An application step of applying an adhesive agent to an application area of a surface of a sintered R-T-B based magnet work, an adhesion step of allowing a particle size-adjusted powder that is composed of a powder of an alloy or a compound of a Pr—Ga alloy which is at least one of Dy and Tb to the application area of the surface of the sintered R-T-B based magnet work, and a diffusing step of heating it at a temperature which is equal to or lower than a sintering temperature of the sintered R-T-B based magnet work to allow the Pr—Ga alloy contained in the particle size-adjusted powder to diffuse from the surface into the interior of the sintered R-T-B based magnet work are included. The particle size of the particle size-adjusted powder is set so that, when powder particles composing the particle size-adjusted powder are placed on the entire surface of the sintered R-T-B based magnet work to form a particle layer which is not less than one layer and not more than three layers, the amount of Ga contained in the particle size-adjusted powder is in a range from 0.10 to 1.0% with respect to the sintered R-T-B based magnet work by mass ratio.

摘要： The devices, systems, and methods of the present disclosure are directed to powder spreading and binder distribution techniques for consistent and rapid layer-by-layer fabrication of three-dimensional objects formed through binder jetting. For example, a powder may be spread to form a layer along a volume defined by a powder box, a binder may be deposited along the layer to form a layer of a three-dimensional object, and the direction of spreading the layer and depositing the binder may be in a first direction and in a second direction, different from the first direction, thus facilitating rapid formation of the three-dimensional object with each passage of the print carriage over the volume. Powder delivery, powder spreading, thermal energy delivery, and combinations thereof, may facilitate consistently achieving quality standards as the rate of fabrication of the three-dimensional object is increased.

摘要： In an example implementation, a method of operating a sintering furnace includes receiving information about a green object load to be sintered in a sintering furnace, determining a sintering profile based on the information, and performing a sintering process according to the sintering profile. During the sintering process, a sensor reading that indicates a degree of densification of a green object in the load is accessed from a densification sensor. The method includes initiating a cool down phase of the sintering process if the sensor reading has reached a target sensor reading.

摘要： Certain aspects of the technology disclosed herein include an apparatus and method for forming nanoparticles. The method includes a mechanical milling process induced by aerodynamic, centrifugal, and centripetal forces and further augmented by ultrasound, magnetic pulse, and high voltage impact. A nanoparticle mill having an atmospheric and luminance controlled environment can form precisely calibrated nanoparticles. A nanoparticle mill can include first aerodynamic vane configured to rotate around a central axis of the nanoparticle mill in a first direction, and a second aerodynamic vane configured to rotate around the central axis in a second direction. An aerodynamic shape of an aerodynamic vane can be configured to cause particles within the nanoparticle mill to flow around the aerodynamic vane. The nanoparticle mill can include a primary product line, a nanoparticle sampling line, a particle programming array, a solidifying chamber, or any combination thereof.

摘要： Described are cementitious reagent materials produced from globally abundant inorganic feedstocks. Also described are methods for the manufacture of such cementitious reagent materials and forming the reagent materials as microspheroidal glassy particles. Also described are apparatuses, systems and methods for the thermochemical production of glassy cementitious reagents with spheroidal morphology. The apparatuses, systems and methods makes use of an in-flight melting/quenching technology such that solid particles are flown in suspension, melted in suspension, and then quenched in suspension. The cementitious reagents can be used in concrete to substantially reduce the CO2 emission associated with cement production.
