    • A method of forming a stiffened panel from first and second metal sheets, at least the first sheet being capable of both superplastic deformation and diffusion bonding, and also provided with at least one control region of different thickness compared with other regions of the sheet, includes the steps of:attaching the sheets together at a series of attachment lines across their faces, the attachment lines and the control region or regions being in predetermined relationship with one another, placing the attached sheets in a mould and heating to within that temperature range within which superplastic deformation and diffusion bonding takes place,urging those areas of the first sheet between the attachment lines away from the second sheet by a common differential pressure at a rate within that range of strain rates at which superplastic deformation occurs to form a series of cavities between the two sheets such that peripheral parts of those areas urged away from the second sheet form side walls of neighboring cavities and become diffusion bonded together to provide internal stiffeners of the finished panel,the control region or regions effecting local modification of the rate of superplastic deformation such that the internal stiffeners adopt a desired configuration and location.
    • 一种从第一和第二金属板形成加强板的方法,至少所述第一片材能够超塑性变形和扩散结合,并且还具有与片材的其它区域相比不同厚度的至少一个控制区域, 以下步骤:在一系列连接线穿过其表面连接片材,连接线和控制区域或彼此处于预定关系的控制区域或区域,将附着的片材放置在模具中并加热至该温度范围内 发生超塑性变形和扩散接合,通过普通的压差将第一片材的附着线之间的第一片材​​区域推压到超塑性变形发生的应变速率范围内的速率,以形成一系列空腔 在两个片材之间,使得这些区域的周边部分被迫离开第二片材形式 邻近空腔的侧壁并且扩散结合在一起以提供成品面板的内部加强件,控制区域或区域实现超塑性变形速率的局部改变,使得内部加强件采用期望的构造和位置。

    • A method of making a stiffened panel including subjecting two metal sheets, at least one capable of superplastic deformation and diffusion bonding, which are positioned face to face, to a bonding and deforming process during which the sheets are joined to one another at a series of spaced joint lines across their faces, the joint lines being interrupted by non-joined regions along their lengths but being otherwise substantially continuous, and during which parts of at least said one sheet between the joint lines and the non-joined regions thereof are superplastically deformed in a mould to form a series of cavities between the two sheets, portions of at least said one sheet on respective sides of each of the joint lines and the non-joined regions thereof being moved to form sidewalls of two neighboring cavities, these sidewalls being urged to lie adjacent one another over substantial parts of their areas, so that they become diffusion bonded, one to another, to form a common sidewall of neighboring cavities, the non-joined regions of the joint lines each forming a generally circular or part-circular aperture in each sidewall of a diameter similar to the length of the non-joined region.
    • 一种制造加强板的方法,包括将两个金属板,至少一个能够相对定位的超塑性变形和扩散粘合的表面对接在一起的接合和变形过程中,其中片材以一系列的方式彼此接合 在它们的表面上的间隔的接合线,接合线被沿其长度的非接合区域中断,但是基本上是连续的,并且在接合线和非接合区域之间的至少一个片材的部分被超塑性变形 在模具中以在两个片材之间形成一系列空腔,每个接合线及其非接合区域的相应侧上的至少所述一个片材的部分被移动以形成两个相邻空腔的侧壁,这些侧壁为 促使它们彼此相邻地邻接在它们的区域的大部分上,使得它们彼此扩散粘合以形成共同的侧壁o f相邻的腔,接合线的非接合区域各自在每个侧壁中形成与非接合区域的长度相似的直径的大致圆形或部分圆形的孔。
