FATIGUE, CREEP AND STRESS-RUPTURE PROPERTIES OF TI-13V-11CR-3AL TITANIUM ALLOY (B120-VCA)

08/1966;

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.
