This program has demonstrated the feasibility of producing titanium airframe components by hot isostatic pressing HIP of titanium alloy powder. Task 1 culminated in the manufacture of an F-14A fuselage brace to near net shape with critical dimensions within the print tolerance. In addition, Task 2 demonstrated that aerospace design requirements could be met by Ti-6Al-6V-2Sn and Ti-6Al-4V as produced by HIP. Tensile, fatigue and toughness data are presented, which show that annealed plate properties can be attained or exceeded. Excellent fracture toughness K1c was obtained for Ti-6-6-2. Recommendations are presented for the manufacture of a pilot lot as the continuation of the present effort. Author
