Fatigue, Creep, and Stress-Rupture Properties of Several Super Alloys.

Abstract

A fatigue, creep, and stress-rupture testing program was conducted on bar specimens of Rene 41 and Inconel X-750 and on sheet specimens of Magnesium Alloy HK31A-H24, and Titanium Alloys, Ti-4Al-3Mo-1V and Ti-6Al-4V. Tests were conducted at room temperature and at appropriate elevated temperatures under axial-stress conditions and at various combinations of mean and alternating stresses. Notched as well as smooth specimens were tested. The fatigue data are presented in the form of S-N diagrams, and the effects of various combinations of alternating and mean stresses are 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. (Author)
