  • Patent number: 9645125
    Abstract: A method of measuring an atmosphere in a guest vacuum chamber of a vacuum tool includes measuring a first composition of the atmosphere in the host vacuum chamber using a residual gas analyzer (RGA). The host and guest vacuum chambers are not coupled during the measuring of the first composition. The host vacuum chamber is coupled to the guest vacuum chamber, so the atmospheres in each can mix in the host vacuum chamber. A second composition of the atmosphere in the host vacuum chamber is measured using the RGA after the chambers are coupled. Using a processor, a composition of the guest atmosphere is automatically determined using the measured first and second compositions. A vacuum tool can include the host and guest chambers, the valve, the RGA, and a processor configured to control the valve to carry out this or other methods.

To perform stabilization of a second sample of the shape memory alloy, a first sample of the shape memory alloy is selected for isobaric treatment and the second sample is selected for isothermal treatment. When applying the isobaric treatment to the first sample, a constant stress is applied to the first sample. Temperature is also cycled from a minimum temperature to a maximum temperature until a strain on the first sample stabilizes. Once the strain on the first sample stabilizes, the isothermal treatment is performed on the second sample. During isothermal treatment, different levels of stress on the second sample are applied until a strain on the second sample matches the stabilized strain on the first sample.

  • Patent number: 8329464
    Abstract: The present disclosure uses different kinds of surface treatment processes on titanium-made dental implants. The growth and attachment conditions of bone cells (MC3T3-E), fibroblasts (NIH 3T3) and epidermal cells (XB-2) on the metal surface of titanium slices with different surface treatments are observed. Tetra-calcium phosphate is used to perform secondary sand-blasting process to clean up the metal surface and provide calcium ions for osteoblastoma physiology. Thus, by adjusting the cells adhesive and proliferative abilities, the success rate of the clinical applications in dental implant is improved.

  • Patent number: 8296081
    Abstract: The present invention provides a method for obtaining material information regarding steel sheet for shipping over the entire length of the steel sheet for shipping without spending too much time and effort, providing detailed material information in large volumes to a user through a computer and network, and having the user utilize the same. Specifically, it estimates the mechanical properties of temper rolled steel sheet based on the actual rolling data in a skinpass mill installed at the exit side of the continuous annealing line or galvanization facility and provides the estimated mechanical properties through the host computer and network to the user of the steel sheet. The user can use the estimated material information so as to remove the parts defective in mechanical properties or change the press forming conditions of the steel sheet. Further, the user can feed back information to the steel sheet manufacturer.

  • Patent number: 8280531
    Abstract: A method and computer program for the control of the heat treatment of batches of metal workpieces for increasing the degree of automation of industrial furnace plants presumes an identical batch layout, an identical treatment program, and an identical article geometry of metal workpieces and relates it to a model batch, which has been run using batch thermoelements. The model batch becomes the foundation for a new batch. Through the assumption of program parameters of the actually run process of the model batch into the program of the new batch to be run, new batch thermoelements are not required for the new batch to be run.

  • Publication number: 20120211126
    Abstract: An induction hardening heat treatment method comprises the steps of induction heating a metal part or component, particularly a part fabricated of a high strength material, and then exposing the part to a sequence or series of partial, intermittent or interrupted quenches. Such intermittent or interrupted quenching achieves the necessary change in surface temperature with time to achieve a martensitic transformation of the surface adjacent metal or material while minimizing surface to core temperature differentials during the process which could result in cracking of the part, especially if it is fabricated of high strength materials.

    Abstract: A microstructure detector and in-situ method for real-time determination of the microstructure of a material undergoing alloying or other phase transformation. The method carried out by the detector includes the steps of: (a) detecting light emitted from a plasma plume created during phase transformation of a material; (b) determining at least some of the spectral content of the detected light; and (c) determining an expected microstructure of the transformed material from the determined spectral content. Closed loop control of the phase transformation process can be carried out using feedback from the detector to achieve a desired microstructure.

    Abstract: A shape memory alloy for use as a mechanical component is formed of an intermetallic material having a low apparent modulus and a high hardness. The intermetallic material is conditioned to have a stable, superelastic response without irrecoverable deformation while exhibiting strains of at least 3%. The method of conditioning the intermetallic material is described. Another embodiment relates to lightweight materials known as ordered intermetallics that perform well in sliding wear applications using conventional liquid lubricants and are therefore suitable for high performance mechanical components such as gears and bearings.

    Abstract: In a process for producing a large single-crystal component or directionally solidified component made of a nickel-based superalloy, the component is first cast into shape in a known manner to form a microstructure comprising dendrites, and then solution annealing for homogenizing the cast microstructure of the component and two-stage precipitation heat treatment are carried out. In order to avoid chemical inhomogeneities and internal stresses caused thereby, a HIP process with a pressure of higher than 160 MPa is carried out following the solution annealing.

  • Patent number: 8088233
    Abstract: A method of characterizing phase transformations of a shape memory material specimen entails recording data from the specimen during heating and cooling. The temperature of the specimen is changed in a first direction to a first temperature sufficient to define a first inflection and a second inflection in the data being recorded. The temperature of the specimen is changed in a second direction to a second temperature sufficient to define a third inflection in the data. The third inflection is formed by overlapping primary and secondary sub-inflections. The temperature of the specimen is changed in the first direction to a third temperature sufficient to define the first inflection but not sufficient to define the second inflection. The temperature of the specimen is then changed in the second direction to a fourth temperature sufficient to define the secondary sub-inflection in the data being recorded.

  • Publication number: 20110247729
    Abstract: A method for improving a residual stress in a pipe includes improving the residual stress in the inner surface to the compressive direction by rapid cooling of the inner surface after heating of the pipe. The heating is to heat a vicinity of a welded part of the pipe from the outer surface to raise the temperature to a construction temperature. The rapid cooling is to rapidly cool the inner surface in the vicinity of the welded part by supplying cooling water into the pipe. The heating and the rapid cooling are repeated twice or more. A method for construction management includes determining whether construction has been executed properly based on a maximum value of a lowering rate of an outer surface temperature of the pipe when the cooling water is supplied for the rapid cooling of the inner surface and a thickness of the pipe in a measuring position of the outer surface temperature.
