摘要： A method of superplastic forming of titanium packs and an associated assembly is provided. The titanium packs can include sheets having different granular structures so that the different sheets are adapted to superplastically form at different temperatures. One or more of the sheets can be formed at a temperature that is below the superplastic forming temperature of another sheet in the pack. In some cases, the occurrence of markoff can be reduced or eliminated.

摘要： A method for superplastically forming and/or diffusion bonding a structural member and an associated structural member are provided. The structural member is formed at least partially of titanium, e.g., Ti-6Al-4V, and has a fine grain structure. For example, the grain size of the material of the structural member can be less than 2 micron. The member can be superplastically formed and/or diffusion bonded at a reduced temperature, thereby potentially reducing the thermal energy required for forming and bonding, and also reducing the effects of heating on the structural member and the forming apparatus. In addition, the structural member can be formed at an increased strain rate.
摘要翻译：提供了一种用于超塑性地形成和/或扩散结合结构件和相关结构件的方法。结构构件至少部分地由钛形成，例如Ti-6Al-4V，并且具有细晶粒结构。例如，结构构件的材料的粒径可以小于2微米。该构件可以在降低的温度下被超塑性地形成和/或扩散接合，从而潜在地降低了形成和结合所需的热能，并且还降低了对结构构件和成形装置的加热效果。此外，结构构件可以以增加的应变速率形成。

摘要： The invention provides methods of superplastic forming and diffusion bonding and a gas inlet tube that facilitates the methods which produce structures that are substantially mark off free. Methods include disposing a sealed pack into a die having a patterned surface and an opposite surface; applying a first pressure within the die around an outside of the pack; applying a second pressure within the pack, the second pressure exceeding the first pressure; and forming the pack by superplastic deformation into a diffusion-bonded structure. Further, a gas inlet tube is provided having an inner tube and an outer tube, where the outer tube is weldable to the pack in a gas tight seal.

摘要： A method for providing a stop-off material on a workpiece is provided, as is an associated assembly. A maskant is provided on the workpiece such that a first portion of the workpiece is exposed and a second portion of the workpiece is covered by the maskant. The stop-off is then disposed, with the maskant on the workpiece preventing the stop-off from being applied to the second portion of the workpiece. The maskant is removed from the workpiece leaving the stop-off disposed on a select portion of the workpiece. The removal of the maskant can leave the workpiece substantially free of debris. Thereafter, the workpiece can be further processed, e.g., by diffusion bonding, with the stop-off preventing diffusion bonding of part of the workpiece.
摘要翻译：提供了一种用于在工件上提供停止材料的方法，如相关联的组件。在工件上设置掩模，使得工件的第一部分被暴露，并且工件的第二部分被掩蔽剂覆盖。然后将掩模放置在工件上，防止阻挡件被施加到工件的第二部分上。将掩模从工件移除，离开设置在工件的选择部分上的停止。去除掩模可以使工件基本上没有碎片。此后，可以通过例如通过扩散接合进一步处理工件，同时防止部分工件的防止扩散接合。
