FATIGUE, CREEP AND STRESS-RUPTURE PROPERTIES OF NICROTUNG, SUPER A-286, AND INCONEL 718

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.
