A typical embodiment of the invention discloses a technique for joining structures. For instance, to provide a heat-resistant vacuum seal in a photomultiplier tube, a mechanically deformable material is interposed between tube components. The deformable material is seated in complementary grooves formed in opposing component surfaces. The components then are compressed together with sufficient force to exceed the elastic limit of the interposed material in order to distort the material and enable it to flow plastically into the grooves and thereby lock the components together.
