    • A method of quenching a material by injecting a cryogenic fluid into a cooling stream and simultaneously venting gas from the cooling stream, in order to maintain a desired target pressure in a chamber containing the material. In a examplary application of the method, the quenching is a step in the heat-treatment of a metal and the chamber is part of a vacuum furnace. Also disclosed is a method of supplying a cryogenic fluid to a process in which the amount of cryogenic fluid necessary to perform the process is transferred from a storage vessel to a supply vessel via a supply line, after which the supply line is closed. An elevated pressure is maintained by vaporization of a relatively small amount of the cryogenic fluid that is allowed to build in a pressure vessel that is in fluid communication with the supply vessel.
    • 一种通过将低温流体注入冷却流中并同时从冷却流排出气体来淬火材料的方法,以便在包含该材料的腔室中保持所需的目标压力。 在该方法的示例性应用中,淬火是金属热处理中的一个步骤,该室是真空炉的一部分。 还公开了一种将低温流体供应到其中执行该过程所需的低温流体的量经由供应管线从储存容器传送到供应容器的过程之后供应管线关闭的方法。 通过相对少量的低温流体的蒸发来维持升高的压力,所述低温流体被允许建立在与供应容器流体连通的压力容器中。

    • Method of processing a workpiece comprising (a) providing a tool and a workpiece, wherein the workpiece has an initial shape; (b) placing the workpiece and the tool in contact to form an interface, applying force to the tool and/or the workpiece, and moving the tool and/or the workpiece to effect a change in the initial shape of the workpiece; (c) applying a lubricant to any area on a surface of the tool and/or to any area on a surface of the workpiece while the workpiece and the tool are in contact; and (d) applying a cryogenic fluid to any area on the surface of the tool and/or to any area on the surface of the workpiece while the workpiece and the tool are in contact.
    • 一种处理工件的方法,包括:(a)提供工具和工件,其中所述工件具有初始形状; (b)将工件和工具接触以形成界面,向工具和/或工件施加力,并移动工具和/或工件以实现工件的初始形状的改变; (c)当工件和工具接触时,将润滑剂施加到工具表面上的任何区域和/或工件表面上的任何区域上; 和(d)当工件和工具接触时,将低温流体施加到工具表面上的任何区域和/或工件表面上的任何区域。
