The Stress Behavior of Three Advanced Nickel-Base Superalloys during High-Temperature, Low-Cycle Fatigue

摘要

This report is a compilation of data on stress behavior as a function of cycles obtained during high-temperature, low-cycle fatigue tests on three advanced Ni-base superalloys--Rene 95, AF-115, and AF2-1DA. The data are presented in both tabular and graphical formats. The materials studied are those used for jet-engine turbine disks, and the fatigue tests were conducted at their operating temperatures. The purpose of this report is to make the test data available to the technical community. No discussion is presented on an analysis or an understanding of the data, although some observations are included. (Author)
