DEVELOPMENT OF HIGH PERFORMANCE ROCKET MOTOR CASE

Abstract

The evaluation of material for possible application to rocket motor cases was continue . Data on Ti-13V-11Cr-3Al alloy are included. Data on fracture energy testing and retests of stress corrosion specimens without edge seal protection are reported on JLS 300 alloy. Retesting of the initial heats of 20 and 25% Ni steels incorporating modified heat treatments to improve mechanical properties was accomplished. Results of tensile tests on AM 359 material are reported. Results of testing of uniaxial weld joint specimens of AM 355-PH 15-7 Mo material utilizing a combination of resistance and fusion welding, are included. Work on uniaxial fusion welded butt joints with W inert arc and electron beam processes was continued.
