FATIGUE, CREEP AND STRESS-RUPTURE PROPERTIES OF TI-13V-11CR-3AL TITANIUM ALLOY (B120-VCA)
ABSTRACT A fatigue and creep-rupture testing program was conducted on solution-treated and aged sheet specimens of titanium alloy B-120VCA at room and elevated temperatures. Data on aged bar stock, previously tested, are also included for comparison. All tests were conducted in axial-stress machines with various combinations of alternating and mean stresses. Notched as well as smooth specimens were used. The data are presented in the form of S-N and creep rupture diagrams, and the effect of various combinations of alternating and mean stresses is shown by means of constant-life diagrams. Creep data are given in the form of creep-time curves, and for design purposes, creep strength curves are presented.

ABSTRACT: The fatigue, creep, and stress rupture properties of three super alloys; Nicrotung, Super A-286, and Inconel 718 were determined at elevated temperatures. The specimens of Nicrotung were investment cast, Super A-286 were machined from bar stock, while the Inconel 718 was tested in sheet form. The specimens were tested in axial-stress machines. Fatigue and stress-rupture data are presented in the form of S-N diagrams, and the effect of combinations of alternating and mean stresses is shown by means of stress range diagrams. Creep data are given in the form of creep-time curves, and for design purposes creep strength curves are presented.05/1966;
