摘要： A method for manufacturing a metal structure (130) for use in a downhole assembly comprises plastically deforming at least a portion of the metal structure (130); and heating at least the deformed portion of the metal structure to a temperature below its critical and/or transformation temperature. An assembly for performing the method comprises a production fixture (370) configured to receive the metal structure (130), wherein the production fixture is adapted to undergo heating to a temperature below and/or up to the critical and/or transformation temperature of the metal structure. By heating at least the deformed portion of the metal structure to a temperature below its critical and/or transformation temperature, the metal structure may undergo stress relief, which may help prevent undesirable movement of deformed portion, e.g. collet fingers of a catching apparatus, against the direction of deformation after impact(s) and/or shock(s) from moving objects, in use.
摘要翻译：用于制造用于井下组件的金属结构（130）的方法包括使金属结构（130）的至少一部分塑性变形; 以及至少将所述金属结构的变形部分加热到低于其临界和/或转变温度的温度。用于执行该方法的组件包括构造成接收金属结构（130）的生产夹具（370），其中生产夹具适于经受加热至低于和/或高于其的临界和/或相变温度金属结构。通过将金属结构的至少变形的部分加热到低于其临界和/或相变温度的温度，金属结构可能经历应力释放，这可有助于防止变形部分的不希望的移动，例如，捕捉装置的夹头，在使用中抵抗来自移动物体的冲击和/或冲击之后的变形方向。
