Abstract: A method of fabricating headed-shank parts from high-strength two-phase titanium alloys characterized by using an oxalate coating capable of forming a fine-crystalline salt film, cold shaping the shank by reduction, and simultaneous heading and rolling the shank and the radius under the head.

The use of the oxalate coating and of the cold-shaping speeds within the above-mentioned limits has made it possible to use automatic cold-heading machines thus raising the productivity of the process 20 - 30 times and producing parts of a higher quality. The method can be widely used for making such parts as rivets, bolts, screws, rivet-bolts and core rivets.

Abstract: An adjustable flange for a dry lube variable speed sheave assembly having an unmachined bore is centered on a vacuum fixture. A thin dry bearing material is secured and located axially and radially within the flange bore and the annular space between the thin dry bearing material and the flange bore is filled with a high compressive modulus material such as epoxy.

In accordance with a variation of the method, the separately formed thin dry bearing material is eliminated and a suitable dry lube material is mixed with the epoxy-like cement prior to injecting the same into said annular space. Following curing, this material becomes the dry lube bearing of the flange.
