1. Introduction Titanium 13-11-3, AMS 4917, AMS 4959, AMS 6926, MIL F-83142, MIL T-9046, MIL T-9047, UNS R58010

Titanium 13-11-3 is a heat-treatable, beta-alloy titanium generally considered for high-strength applications.

Mainly used in high-strength airframe components, including wire springs.

It combines good fabricability with excellent corrosion resistance and mechanical properties.

This alloy can be hot or cold-formed and will exhibit characteristics equivalent to those found in a 1/8 to 1/4 hard austenitic stainless steel.

Hot forming will reduce both the spring back and required forming forces and will increase the overall ductility of the material.

The cold working characteristics of this alloy are similar to those found in austenitic stainless steels. In multiple forming operations, intermediate stress relieving is recommended to offset the alloy's tendency to work hard. Post-work annealing is recommended to reattain maximum performance characteristics.

As a family, titanium and its alloys have developed a mystique as a nightmare to a machine. This is simply not the case. Experienced operators have compared its characteristics to those found in 316 stainless steel. Recommended practice includes high coolant flow(to offset the material's low thermal conductivity), slow speeds, and relatively high feed rates. Tooling should be tungsten carbide designations C1-C4 or cobalt-type high-speed tools.
